MEMORY SYSTEM AND METHOD

摘要

According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller reads write data associated with a first write command from a host memory by a unit of a first size in response to the first write command from a host. The host memory is included in the host. In a case where the size of first data not yet read from the host memory out of the write data is less than a second size, in response to a second write command, the controller reads second data of the second size and writes the read second data into the nonvolatile memory. The second data includes the first data and third data included in write data associated with the second write command. After writing the second data into the nonvolatile memory, the controller transmits a notice for the first write command to the host.

主权项

1. A memory system which is connectable to a host, comprising:
a nonvolatile memory; and a controller that,
in response to a first write command from the host, reads write data associated with the first write command from a host memory by a unit of a first size, the host memory being included in the host, and,in a case where the size of first data not yet read from the host memory out of the write data is less than a second size, in response to a second write command subsequent to the first write command, reads second data of the second size from the host memory, the second data including the first data and third data, the third data being included in write data associated with the second write command, writes the read second data into the nonvolatile memory and, after writing the second data into the nonvolatile memory, transmits a notice for the first write command to the host.
