Abstract:
Program disturb error logging and correction for a flash memory including a computer implemented method for storing data. The method includes receiving a write request that includes data and a write address of a target page in a memory. A previously programmed page at a specified offset from the target page is read from the memory. Contents of the previously programmed page are compared to an expected value of the previously programmed page. Error data is stored in an error log in response to contents of the previously programmed page being different than the expected value of the previously programmed page, the error data describing an error in the previously programmed page and the error data used by a next read operation to the previously programmed page to correct the error in the previously programmed page. The received data is written to the target page in the memory.
