Optimistic read operation

A method of executing a read operation in a non-volatile memory system, the method comprising:

• receiving, with a front end module, a host read request to read a requested data set, the host read request identifying a logical address associated with the requested data set,
• performing, with a sensing control module of a non-volatile memory die, a first sensing operation on an entry stored in a non-volatile memory array of the non-volatile memory die, the entry mapping the logical address identified in the host read request to a physical address;
• performing with the sensing control module, a second sensing operation on a data set stored in the nonvolatile memory array at the physical address identified in the entry without first performing error correction on a copy of the entry;
• and
• verifying, with a verification module, that a copy of the data set generated in response to the second sensing operation matches the requested data set before the front end module transfers the data set copy to the host.
