Memory device with specified write data size
First Claim
1. A memory device comprising:
- a nonvolatile memory which stores data in units of a write unit comprising cells; and
a controller whichcontrols the nonvolatile memory,partitions memory space of the nonvolatile memory,in response to a request to write write-data to the nonvolatile memory from a host device, requests the host device to transmit a segment of the write-data with a specified size, wherein the write-data segment has a size determined to allow for a size of a set of part of the write-data segment and corresponding additional data to be the largest while smaller than a size of the write unit, and wherein a size of the part of the write-data segment is a division by an integer of the size of the write-data segment, andbefore completion of processing a first command which requests access to a first partition, accepts a second command which requests access to a second partition.

Abstract
According to one embodiment, a memory device includes a nonvolatile memory which stores data in units of a write unit includes cells, and a controller which controls the memory and partitions memory space of the memory. In response to a request to write write-data to the memory from a host, the controller requests the host to transmit a segment of the write-data with a specified size. The write-data segment has a size of an integral multiple of a size determined to allow for a set of the write-data segment and corresponding additional data to be the largest while smaller than the write unit. Before completion of processing a first command which requests access to a first partition, the controller accepts a second command which requests access to a second partition.

12. A memory device comprising:
-
a nonvolatile memory which stores data in units of a write unit comprising cells; and a controller which controls the nonvolatile memory, partitions memory space of the nonvolatile memory, in response to a request to write write-data to the nonvolatile memory from a host device, requests the host device to transmit a segment of the write-data with a specified size, wherein the write-data segment has a size to allow the write-data segment to be written in a write unit to fit the end of the write unit, and before completion of processing a first command which requests access to a first partition, accepts a second command which requests access to a second partition. - View Dependent Claims (13, 14, 15, 16)
