STORAGE CONTROL APPARATUS, DATA STORAGE APPARATUS AND METHOD FOR STORAGE CONTROL

摘要

According to one embodiment, a storage control apparatus includes a first buffer controller and a second buffer controller. The first buffer controller is configured to store data of a first unit in each of data buffer regions, and the data of the first unit is transmitted from a host and written in a nonvolatile memory, or read from the nonvolatile memory and transmitted to the host. The second buffer controller is configured to independently transmit data of a second unit from the data buffer region corresponding to a bank prepared for transmission when data is written in the nonvolatile memory, and to independently transmit data of the second unit from a bank to be read to the data buffer region corresponding to the bank to be read when data is transmitted to the host.
