Optimistic read operation

摘要

A non-volatile memory system may include a non-volatile memory die storing a requested data set that a host requests to be read. In response to the host request, a copy of a data set may be retrieved from the non-volatile memory die without performing error correction on an entry identifying a physical address where the data set is stored. If the data set copy matches the requested data set, the data set copy may be sent to the host. If the data set copy does not match the requested data set, then error correction may be performed on a copy of the entry to identify the correct physical address where the requested data set is stored. A copy of the requested data set may then be retrieved and sent to the host.
