READ DISTRIBUTION IN A THREE-DIMENSIONAL STACKED MEMORY BASED ON THERMAL PROFILES

摘要

A memory controller may receive a plurality of thermal profiles from a plurality of three-dimensional (3D)-stacked memory chips, where the plurality of thermal profiles include thermal profile data for the memory chips, where the thermal profile data includes a memory chip usage data and a location data for each of the memory chips, and where the memory chips include a first memory chip and a second memory chip. The memory controller may generate a first predicted memory chip usage data and location data by analyzing the usage data and location data of the thermal profile data. A second predicted memory chip usage data and location data may be generated. Based on the predicted memory chip, fractional memory chip read propensity data may be generated. The memory controller may distribute, according the first fractional memory chip read propensity distribution, memory chip read operations.
