Towards attaining these objectives for practical implementations, various techniques to mitigate the specific reliability challenges associated with STT-MRAM elements are surveyed, classified, and assessed in this article. Cost and suitability metrics assessed include the area of nanomagmetic and CMOS components per bit, access time and complexity, sense margin, and energy or power consumption costs versus resiliency benefits. Solutions to the reliability issues identified are addressed within a taxonomy created to categorize the current and future approaches to reliable STT-MRAM designs. A variety of destructive and non-destructive sensing schemes are assessed for process variation tolerance, read disturbance reduction, sense margin, and write polarization asymmetry compensation. The highest resiliency strategies deliver a sensing margin above 300mV while incurring low power and energy consumption on the order of picojoules and microwatts, respectively, and attaining read sense latency of a few nanoseconds down to hundreds of picoseconds for non-destructive and destructive sensing schemes, respectively.<\/jats:p>","DOI":"10.1145\/2997650","type":"journal-article","created":{"date-parts":[[2017,4,20]],"date-time":"2017-04-20T12:05:21Z","timestamp":1492689921000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Survey of STT-MRAM Cell Design Strategies"],"prefix":"10.1145","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5998-8795","authenticated-orcid":false,"given":"Soheil","family":"Salehi","sequence":"first","affiliation":[{"name":"University of Central Florida, Orlando, FL"}]},{"given":"Deliang","family":"Fan","sequence":"additional","affiliation":[{"name":"University of Central Florida, Orlando, FL"}]},{"given":"Ronald F.","family":"Demara","sequence":"additional","affiliation":[{"name":"University of Central Florida, Orlando, FL"}]}],"member":"320","published-online":{"date-parts":[[2017,4,20]]},"reference":[{"key":"e_1_2_1_1_1","article-title":"Energy and delay tradeoffs of soft error masking for 16nm FinFET logic paths: Survey and impact of process variation in near threshold region","author":"Alghareb F.","year":"2016","journal-title":"IEEE Trans.
