Method and apparatuses for customizable error correction of memory

摘要

Described herein are a method and apparatuses for providing customizable error correction for memory arrays. In one embodiment, an apparatus includes a memory device having a memory array to store data and an analog to digital sense unit coupled to the memory array. The analog to digital sense unit senses analog signals associated with the memory array and converts the analog signals into distributions of digital values. An error-correcting code (ECC) unit receives the distributions of digital values from the analog to digital sense unit. A configurable non-volatile look-up table generates ECC parameters including error probability data and provides the ECC parameters to the ECC unit for error correction. The error probability data has error probability values that are associated with the distributions of digital values. The ECC unit executes an ECC algorithm to provide error correction using the error probability data.
