heteroGeneous integRated magnetic tEchnology using multifunctional standardized sTack (MSS)

Deliverables

First VerilogA model of the magnetic device to initiate the design steps

This first model, written in VerilogA to be compatible with all the standard electrical simulators, will take into account the main physical effects required to model the logic, memory, analog and RF functionalities. At this stage, the model will remain relatively generic and will be tuned later according to the progress of the technology.

Consolidated VerilogA model of the magnetic device, for optimized design

This consolidated model will be based on the preliminary model, but tuned using the characterization results of the technology, for better accuracy. A specific model card will be developped to adapt the model to this technology.

Consolidated standard cell library

The library will contain a set of Standard Cells (SC), elementary logic functions to synthetize more complex logic circuits. The variety of the cells will represent various design corners (low-power area efficient, fast, resilient cells...) and cover different output capacitive loads.

Magnetic technology files and integration in the design suite for the physical verifications

This technology files are part of a Process Design Kit (PDK) allowing to integrate the technology in the standard design suites of microelectronics. It will contain in particular : - Technology files containing the design rules provided by Spintec or Tower for Design Rules Checking, -technology files giving the informations about the technology to perform extraction of the circuit.

Management plan

This Management Plan is a mandatory deliverable of the GREAT project, but is also considered as a key feature for the management of the project. It has been designed to be the official Project Handbook for any participant to GREAT. Any project member (project managers, engineer, scientist, etc.) should read it at least once. The main management features described in this document is: 1) Management structures that describe the formal project management organization and responsibilities sharing. 2) Management processes which are working routines and practices that each person participating to the project should apply. 3) Management tools that are techniques, medium or reference documents that help the implementation of the management process.

2nd Management Periodic Report

The Management Periodic Report provides an explanation of personnel costs, subcontracting and any major costs incurred by each beneficiary, such as the purchase of important equipment, travel costs, large consumable items, etc., linking them to work packages.

Validation of the first test chip for each IP block.

This report will include all public information regarding the design of IP blocks within tasks 3.1 (Sensors) and 3.3 (MSS-controlled digital tuning circuits). MTJ-based sensors should include magnetic-field sensors for compass applications and some additional sensors that use the magnetic field as an intermediate physical magnitude. On this later principle, two applications have been identified: a voltmeter with a high galvanic isolation and an ammeter. One particular targeted IP block is a smart power-PAD that would be able to monitor the instantaneous power delivered at the better or that would be able to inform instantaneously if the delivered power goes higher than a fixed an/or programmable threshold is reached. Digital tuning circuits will include a family of analog elementary functions (voltage and current sources, OTA) that will include a non-volatile digital tuning of the main characteristic (output voltage or current, transconductance of the OTA) to replace fuse-based approach when compensating for variability. Detailed and restricted information will be given in a restricted annex.

1st Community Periodic Contribution

A report on the distribution of the European Union financial contribution between beneficiaries will be submitted after GREAT first period.

Report about demonstration of the sensor functionality using the MSS stack

This report will present the test results of the MSS stack used for sensor applications. In particular, the following performances will be evaluated: - Sensistivity of the sensor, - Linearity of the response, - Low-hysteresis.

2nd Community Periodic Contribution

A 2nd report on the distribution of the European Union financial contribution between beneficiaries will be submitted after GREAT second period.

Report about demonstration of the memory functionality using the MSS stack

Report about memory functionality, with particular focus on retention versus size and ellipse aspect ratio

Report about demonstration of RF functionality using the MSS stack

Using the MSS stack, magnetic nanopillar devices will be realized and the RF functions investigated. These functions consider the emission of a microwave voltage signal, with properties that are suitable for integration into a PLL (D3.2). Other functions, such as modulation and detection will also be considered were suitable.

2nd Dissemination & Promotion of project results

The Report on dissemination and promotion of the project’s results (including socio-economic impact and target groups for the results of the research) is established on a periodic base. It is a short focus of GREAT exploitable knowledge and summarizes the activities targeting scientific community, industry and general public. It includes 3 summary tables of the dissemination and promotion activities in these 3 fields. This document aims at screening the different results partners have obtained thanks to this project and how they are willing to exploit but also disseminate it.

Final IP documentation

This report will include all public information with respect to the designed IP blocks within tasks 3.1 (Sensors) and 3.3 (MSS-controlled digital tuning circuits). Expected and/or obtained performances will be given in a form close to a data sheet for each IP blocks. Detailed and restricted information will be given in a restricted annex.

Report on Ø300mm wafer processing methodology, WiW and WtW uniformity

WiW: TMR and RA uniformity <6% @ RA=10 Ohm.µm². WtW: TMR and RA <4% @ RA=10 Ohm.µm².

Report on hybrid memory hierarchy and processor architecture design techniques providing density, performance, low power and resilience

This report will summarize the results of the hybrid memory hierarchy (Registers, FFs, caches, etc.) analysis for a variety of processor architectures (e.g. GPUs, DSPs, standard many-core microprocessors). The focus will be on resiliency, low-power, high density and performance.

GREAT website

The Partners will establish within the first 6 months a “great.eu” home page on a World Wide Web (www) server accessible via the Internet. In an area restricted to project partners and the European Commission (password protected), it will provide: the “Description of Action” for the contract, work schedules and logistics information, updates on deliverables, news and project report, issues regarding dissemination, also including abstracts of papers and presentations…

One publication on micromagnetic modelling

The publication will analyze via micromagnetic simulations the magnetic behavior of the MTJs of MSS under magnetic field and spin-polarized current.

Project Presentation

The Project Presentation is a short description of GREAT objectives, goals, approach, expected results and participants. The purpose of this document is to use it for dissemination of GREAT and all the information included here will also be included in the project web site.
