Abstract
According to one embodiment, a memory system includes a nonvolatile memory, a buffer, a battery and a processing circuit. The battery stores energy supplied from the outside. The processing circuit, after start of the supply of energy from the outside, starts the acceptance of a request from the outside, starts a process in accordance with the accepted request, and restricts the amount of data in the buffer referring to a voltage of the battery. The process uses the buffer.
Claims20
A memory system comprising:
- a nonvolatile memory;
- a buffer;
- a battery configured to store energy supplied from the outside;
- and
- a processing circuit configured to, after start of the supply of energy from the outside, start the acceptance of a request from the outside, start a process in accordance with the accepted request, the process using the buffer, and restrict the amount of data in the buffer referring to a voltage of the battery.

A memory system comprising:
- a nonvolatile memory;
- a battery configured to store energy supplied from the outside;
- a processing circuit configured to
- write data in the buffer in first mode into the memory after start of the supply of energy from the outside and in a case where the battery being in a first state, the first state being a state where a voltage of the battery is smaller than a set value, and
- write the data in the buffer in second mode into the memory after the start of the supply of energy from the outside and in a case where the battery being in a second state, the second mode being a mode where the number of bits per memory cell is larger than the first mode, the second state being a state where the voltage of the battery is larger than the set value.
