SOFT READ FOR NVM THAT IS SUBJECT TO DESTRUCTIVE READS

Abstract:

An embodiment of an apparatus may comprise a controller coupled to one or more substrates and including circuitry to control access to NVM with a destructive read characteristic, perform a first read of a codeword from the NVM at a first reference voltage of a low confidence zone, perform a second read of the codeword from the NVM at a second reference voltage of the low confidence zone, and assign a lower confidence value to bits of the codeword that have a different value for the first read of the codeword and the second read of the codeword as compared to a confidence value assigned to bits of the codeword that have a same value for the first read of the codeword and the second read of the codeword. Other embodiments are disclosed and claimed.
