Memory apparatus and methods thereof for preventing read errors on weak pages in a non-volatile memory system

摘要

A memory apparatus and methods are provided for preventing read errors on weak pages in a non-volatile memory system. In one example, a method includes identifying a weak page in a non-volatile memory device along a word line, wherein the weak page is partially written with at least some data; buffering data associated with the weak page to a weak page buffer that is coupled in communication with the non-volatile memory device; determining that an amount of data in the weak page buffer has reached a predetermined data level; and writing the data from the weak page buffer into the weak page along the word line in the non-volatile memory device.

1. A method for accessing data in a non-volatile memory system, the method comprising:
writing data into a page of a non-volatile memory device (NVMD) along a word line, wherein the word line is partially written with at least some data such that the page is a weak page; storing the write data associated with the weak page into a weak page buffer as a duplicate weak page; and serving a read request for data in the weak page from the duplicate weak page stored in the weak page buffer.
