CONTROLLER AND MEMORY SYSTEM
According to one embodiment, a controller determines a write operation, when a write request to a memory, a write address and data are received, by comparing an amount of use of a write buffer and a threshold for determining a change of a write operation to the memory. The memory is capable of overwriting first data to second data at an identical physical address of the memory. By the determined write operation, the received data is written to the received write address of the memory.
