SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Optimising DRAM caches for latency in datacenter servers [PDF]

The unyielding growth in the amount of data processed by datacenter servers warrants an unabated increase in cache capacities. Modern servers already dedicate a big proportion of their die real-estate to on-chip caches, with the largest last-level cache (

SpyHammer: Understanding and Exploiting RowHammer Under Fine-Grained Temperature Variations

IEEE Access
RowHammer is a DRAM vulnerability that can cause bit errors in a victim DRAM row solely by accessing its neighboring DRAM rows at a high-enough rate. Recent studies demonstrate that new DRAM devices are becoming increasingly vulnerable to RowHammer, and ...
