Abstract

According to one embodiment, an information processing apparatus includes a nonvolatile memory and a CPU. The CPU stores first data in the nonvolatile memory, performs a first transmission of a write request associated with the first data to the memory system, and stores management data including information equivalent to the write request in the nonvolatile memory. In response to receiving a first response to the write request transmitted in the first transmission, the CPU adds, to the management data, information indicating that the first response has been received. The CPU deletes the first data and the management data in response to receiving a second response to the write request transmitted in the first transmission after receiving the first response.

Claims20

Dependent claims

An information processing apparatus that is connectable to a memory system, the information processing apparatus comprising:

a nonvolatile memory;
and
a processor configured to:
store first data in the nonvolatile memory;
perform a first transmission of a first write request to the memory system, the first write request being associated with the first data;
store first management data in the nonvolatile memory, the first management data including information equivalent to the first write request,
in response to receiving, from the memory system, a first response to the first write request transmitted in the first transmission, add, to the first management data, information indicating that the first response to the first write request transmitted in the first transmission has been received;
and
delete the first data and the first management data from the nonvolatile memory in response to receiving, from the memory system, a second response to the first write request transmitted in the first transmission after receiving the first response.

6 more elements

A method of controlling a memory system, comprising:

storing first data in a nonvolatile memory;
performing a first transmission of a first write request to the memory system, the first write request being associated with the first data;
storing first management data in the nonvolatile memory, the first management data including information equivalent to the first write request;
in response to receiving, from the memory system, a first response to the first write request transmitted in the first transmission, adding, to the first management data, information indicating that the first response to the first write request transmitted in the first transmission has been received;
and
deleting the first data and the first management data from the nonvolatile memory in response to receiving, from the memory system, a second response to the first write request transmitted in the first transmission after receiving the first response.
