NON-VOLATILE MEMORY DEVICE USING EFFICIENT PAGE COLLECTION MAPPING WITH CACHE AND OPERATING METHOD THEREFOR

摘要

Disclosed are a nonvolatile memory device in which m logical pages are stored in one physical page, and a method of operating the same. A nonvolatile memory device according to an embodiment of the present invention is included in a flash translation layer (FTL), and stores at least some data of the write command based on a write command received from a file system. Register of; And a controller for controlling an operation of the plurality of registers based on the write command received from the file system, each of the plurality of registers having a storage space associated with the size of the m logical pages, and the controller If the size of the data of the write command is greater than or equal to a threshold size associated with the size of the m logical pages, the data of the write command is programmed into the nonvolatile memory device, and the size of the data of the write command is the m number of logic pages. If it is smaller than the threshold size associated with the size of a page, data of the write command is stored in the plurality of registers.
