Methods of operating a memory system that include outputting a data pattern from a sector allocation table to a host if a logical sector is indicated as being erased

摘要

A method of operating a memory system includes receiving a read command from a host, where the read command is associated with a logical sector of a memory, determining whether the logical sector of the memory is indicated as being erased in a sector allocation table, if the logical sector of the memory is indicated as being erased, outputting a data pattern from the sector allocation table to the host, and if the logical sector of the memory is not indicated as being erased, reading a physical sector of the memory and outputting data from the physical sector of the memory to the host.

1. A method of operating a memory system, comprising:
receiving a read command from a host, wherein the read command is associated with a logical sector of a memory; determining whether the logical sector of the memory is indicated as being erased in a sector allocation table; and when the logical sector of the memory is indicated as being erased, generating a sector of data from a data pattern in the sector allocation table and outputting the generated sector of data to the host; wherein the generated sector of data is an original sector of data intended to be written to the logical sector of the memory in response to a write command and the data pattern is a portion of the original sector of data.
