摘要

Skyrmion racetrack memory (SK-RM) has demonstrated great potential as a high-density and low-cost nonvolatile memory. Nevertheless, even though random data accesses are supported on SK-RM, data accesses can not be carried out on individual data bit directly. Instead, special skyrmion manipulations, such as injecting and shifting, are required to support random information update and deletion. With such special manipulations, the latency and energy consumption of skyrmion manipulations could quickly accumulate and induce additional overhead on the data read/write path of SK-RM. Meanwhile, injection operation consumes more energy and has higher latency than any other manipulations. Although prior arts have tried to alleviate the overhead of skyrmion manipulations, the possibility of minimizing injections through buffering skyrmions for future reuse and energy conservation receives much less attention. Such observation motivates us to propose the concept of skyrmion vault to effectively utilize the skyrmion buffer track structure for energy conservation through maximizing the lifespan of injected skyrmions and minimizing the number of skyrmion injections. Experimental results have shown promising improvements in both energy consumption and skyrmions' lifespan.
