The concept envisions a cube of stacked memory die, featuring a logic layer to optimize access to memory, which will potentially handle functions currently performed by memory controllers. Furthermore, the logic layer can be optimized and made to include new functions.
Microsoft believes cube memory represents a major step towards increasing memory bandwidth and performance, while cutting power consumption and latency. Micron hopes to deliver the first 2Gb and 4Gb cubes next year, with a bandwidth of 160Gbps.
