发明名称 APPARATUS, SYSTEM, AND METHOD FOR IMPROVING READ ENDURANCE FOR A NON-VOLATILE MEMORY
摘要 Described are an apparatus, system, and method for improving read endurance for a non-volatile memory (NVM). The method comprises: determining a read count corresponding to a block of NVM; identifying whether the block of NVM is a partially programmed block (PPB); comparing the read count with a first threshold when it is identified that the block is a PPB; and when identified otherwise, comparing the read count with a second threshold, wherein the first threshold is smaller than the second threshold. The method further comprises: identifying a block that is a PPB; determining a first word line corresponding to un-programmed page of the PPB; and sending the first word line to the NVM, wherein the NVM to apply: a first read voltage level to word lines corresponding to the un-programmed pages of the PPB, and a second read voltage level to word lines corresponding to programmed pages of the PPB.
