What you will do
With the advent of ‘Big data’ and the concurrent evolution of computing processors, there is an ever-increasing need for scaled memories that can achieve higher densities, smaller form factors and reduced power consumption. Conventional CMOS-based memory devices such as SRAM and DRAM are found to be lacking in this regard due to increasing concerns of leakage and non-idealities in performance metrics. Furthermore, the advent of non-von Neumann-based computing has also increased the demand for memory devices with similar characteristics.
Several alternative memory technologies have been proposed and investigated in the past decade, of which Magnetoresistive Random Access Memory (MRAM) has emerged as one of the most promising solutions. At imec, several flavours of MRAM are being researched including STT-, SOT- and VCMA-MRAM. These technologies, however, rely on individual junctions to store a single bit of information, and therefore are more suited to existing computing architectures. New concepts, such as domain wall-based MRAM (DW-MRAM), are now emerging that utilize novel spintronic phenomena (such as DMI, chirality, etc) to allow the storage and movement of information on continuous magnetic tracks. This concept promises to increase further the memory density while enabling high throughput for high-bandwidth applications such as machine learning.
Circuit design innovations are key to position new memory concepts for success in the application domains of tomorrow. In this regard, an accurate assessment of futuristic/emerging device concepts is necessary early on to make sure the proposed design is competitive compared to the rest of the memory landscape. As a post-doctoral researcher working on the conceptual assessment of DW-MRAM, your role will cover a thorough design-technology co-optimization (DTCO) analysis to evaluate the feasibility of the proposed concept in terms of industry-relevant performance metrics such as power consumption, area coverage and read/write performance. This mainly involves the optimization of Memory bit-cell and array configurations based on pseudo memory pdks for high performance targets while being tolerant to the innate variability of MRAM devices for large arrays/blocks and large voltage budgets to ensure write without disturb. Furthermore, you will also evaluate the practicality of different designs (both traditional von Neumann designs and novel non-von Neumann designs) and benchmark these proposals at circuit-level with existing CMOS-based and emerging MRAM-based solutions. The final goal will also include the assessment of the technology concept on the most practical design. In addition to the memory applications, this research topic will also evaluate the DW-MRAM concept for machine learning applications due to its promise for true analog in-memory computing
What we do for you
We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium.
