Abstract:
1. A memory system, comprising: a nonvolatile memory device; and a controller comprising a working memory and configured to control the nonvolatile memory device, wherein the nonvolatile memory device stores drive data for accessing the nonvolatile memory device and wherein during an initialization operation of the memory system, the controller activates an operation standby signal after loading a sub-portion of the drive data stored in the nonvolatile memory device into the working memory, wherein the controller loads an additional sub-portion of the drive data stored in the nonvolatile memory device into the working memory after activating the operation standby signal, wherein the controller is configured to receive a request from the host, detect a sub-portion of the drive data required to perform an operation indicated by the request, and upon detecting the sub-portion of the drive data required to perform the operation indicated by the request, load the detected sub-portion into the working memory as the additional sub-portion of the drive data, and wherein the size of the additional sub-portion of the drive data is set so that a time of loading the additional sub-portion of the drive data into the working memory is shorter than a response standby time of a host responsive to the operation standby signal.
