System Method and Apparatus for Screening a Memory System

A method of writing data to a memory block comprising:

• receiving user data in a memory controller, the user data to be written to the memory block;
• writing the user data to a buffer in the memory controller;
• writing a screening pattern to at least one screening column in the memory block;
• performing a first memory integrity test;
• writing user data 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;
• performing a second memory integrity test;
• performing a user data integrity test when the screening column data read from the at least one screening column matches the screening pattern in the second memory integrity test;
• outputting a confirmation of writing the user data in the memory block;
• and
• releasing the user data from the buffer in the memory controller.

A memory system comprising:

• at least one memory block;
• a memory controller coupled to the at least one memory block;
• a screening pattern capable of being written to the at least one memory block;
• and
• a memory verification logic including:
• computer readable instructions on computer readable media for performing a first memory integrity test;
• and
• computer readable instructions on computer readable media for writing user data to at least one user data column in the memory block when a screening column data read from at least one screening column in the memory block matches the screening pattern in the first memory integrity test.
