HETEROGENEOUS MEMORY SYSTEM AND DATA COMMUNICATION METHOD IN THE SAME

摘要

Provided are a heterogeneous memory system and a data communication method in the same. The heterogeneous memory system includes a plurality of different kinds of memory cells, and a central processing unit (CPU) configured to communicate with each of the plurality of memory cells using a high-speed serial link technique. The CPU includes a CPU protocol engine that generates and packetizes command data to be transmitted to at least one of the plurality of memory cells, and each of the plurality of memory cells include a memory protocol engine configured to analyze the command data received from the CPU, and a memory controller configured to perform the corresponding operation according to the analysis result in the memory protocol engine.
