STORAGE DEVICE WITH 2D CONFIGURATION OF PHASE CHANGE MEMORY INTEGRATED CIRCUITS

摘要

A storage device, apparatus, and method to write and/or read data from such storage device. The storage device, comprises a channel controller and phase change memory integrated circuits (PCM ICs) arranged in sub-channels, wherein each of the sub-channels comprises several PCM ICs connected by at least one data bus line, which at least one data bus line connects to the channel controller. The channel controller is configured to write data to and/or read data from the PCM ICs according to a matrix configuration of PCM ICs, wherein: a number of columns of the matrix configuration respectively corresponds to a number of the sub-channels, the sub-channels forming a channel, and a number of rows of the matrix configuration respectively corresponds to a number of sub-banks, the sub-banks forming a bank, wherein each of the sub-banks comprises PCM ICs that belong, each, to distinct sub-channels of the sub-channels.
