CACHE MEMORY DEVICE AND DATA PROCESSING METHOD OF THE DEVICE

摘要

A cache memory device is provided. The cache memory device includes a memory including a first cache memory region and a second cache memory region, and a control block. The control block determines a type of data to be received. The control block also performs at least one of transmitting a head of received data to a first cache memory region, transmitting a body of the received data to a second cache memory region and transmitting a tail of the received data to the first cache memory region based on the type of the data to be received.
