PROBLEM TO BE SOLVED: To provide a memory system and a controller improving read processing performance as much as possible.SOLUTION: The memory system includes a NAND memory 1, a RAM (Random Access Memory) 3, and the controller 2 using the RAM 3 to carry out data transfer between a host device 200 and the NAND memory 1. The controller 2 caches data for every write command transmitted from the host device 200, into a write cache 32 provided in the RAM 3, and transfers data for every write command cached in the write cache 32 to the NAND memory 1 while leaving a head portion respectively at predetermined timing. |
