Data storage device and method for operating the same

摘要

An operating method of a data storage device includes receiving a write request, determining whether it is possible to perform a first write operation of simultaneously writing a plurality of bits in each of memory cells coupled to one word line of a nonvolatile memory apparatus, and performing a garbage collection operation for the nonvolatile memory apparatus, according to a determination result, and generating first merged data.

主权项

1. An operating method of a data storage device, comprising:
determining whether or not a first write operation, in which multi-bits are written at once in each memory cell coupled to one word line of a nonvolatile memory apparatus, is available when a write request is received; and generating first merged data for the nonvolatile memory apparatus when it is determined that the first write operation is not available, wherein the determining of whether or not the first write operation is available comprises: comparing a size of write data corresponding to the write request and a reference value; and determining whether the first write operation for the write data is available based on a comparison result.
