Simultaneous statistical multi-subblock verify for nand memories

A system comprising:

• a processor device;
• and
• a storage device coupled to the processor device, the storage device including
• a nonvolatile storage medium having storage cells in subblocks;
• and
• a media controller to program the storage cells and perform a program verify of the storage cells, including to apply a verify read pulse to multiple subblocks simultaneously, count a number of bitlines of the multiple subblocks that do not discharge in response to the verify read pulse, and pass the program verify of the storage cells if the number is within an expected range.

A method for performing read verify in a storage device, comprising:

• programming storage cells of a nonvolatile storage medium;
• and
• performing verify of the storage cells, including
• applying a verify read pulse to multiple subblocks simultaneously;
• counting a number of bitlines of the multiple subblocks that do not discharge in response to the verify read pulse;
• and
• passing the verify of the storage cells if the number is within an expected range.
