Abstract: Program verify can be performed simultaneously on multiple subblocks in a storage device. The program verify occurs after a program operation of the storage cells. The program verify can include application of a verify read pulse to multiple subblocks simultaneously and then a count a number of bitlines of the multiple subblocks that do not discharge in response to the verify read pulse. The program verify passes if the count is within an expected range, instead of requiring all storage cells to pass program verify before moving on. If the number of bitlines not discharging is outside the expected range, the system can perform a second program pass.
