Abstract: A non-volatile memory device includes a sector pass/fail indicator circuit configured to store a pass/fail indicator for each sector in a first block of memory cells. The pass/fail indicator has a first value indicating the respective sector has failed erase verification and has a second value indicating the respective sector has passed erase verification. The sector pass/fail indicator circuit set the respective pass/fail indicators to the second value for one or more sectors in the first block after the respective sectors pass erase verification following a previous block erase operation of the first block. The first block is subjected to subsequent block erase operation where only word lines associated with the sectors having a pass/fail indicator having the first value are biased to the first bias voltage level.

Abstract: A method for reading a nonvolatile memory array including an array of memory cells, each memory cell including a substrate, a control gate, a charge storage element, a source region and a drain region, includes receiving, at an address register, a read command including an address for a memory cell in the array of memory cells and an indication regarding whether the read command is a full page read command or a partial page read command. A starting address for a page including the received address is identified, wherein the page includes multiple rows of memory cells in the array of memory cells. The address register is reset to the starting address for the page. It is determined whether all memory cells in the page are non-programmed. Data indicative of a non-programmed state of the page is output if it is determined that all memory cells in the page are non-programmed.
