Document Type and Number:
WIPO Patent Application WO/2015/114829
Kind Code:
A1
Abstract:
An information processing device is provided with a memory sub-system connected to a host which performs arithmetic processing. The host communicates a write request including data and the type of said data to the memory sub-system. The memory sub-system comprises a first memory, and a second memory in which the size of a data erase unit for erasure of data is larger than the size of a write unit for said data, and which has a larger data capacity than the first memory. On the basis of the type of said data, the memory sub-system writes random access data and data other than random access data into different erase units in the second memory.
