Abstract
A system and method of writing data to a memory block includes receiving user data in a memory controller to be written to the memory block. The user data is first written to a buffer. A screening pattern is written to at least one screening column and a first memory integrity test is performed based on at least one operational aspect of the memory block. The first memory integrity test includes reading screening column data from the at least one screening column and comparing the screening column data read from the at least one screening column to the screening pattern. The user data is written to at least one user data column in the memory block when the screening column data read from the at least one screening column matches the screening pattern in the first memory integrity test.
