Abstract
An invention is provided for ensuring data integrity in a non-volatile memory system, including boot block data integrity during Power On Reset. The invention includes loading data into a buffer, such as a flash buffer, and generating an error detection code for the data utilizing a check code generator located in the memory controller. The error detection code is compared to a previously stored error detection code associated with the data. Then, when the error detection code is different from the previously stored error detection code, a correction pattern is calculated and applied to the data directly in the buffer for the non-volatile memory.
