Abstract: An apparatus for concurrent test of a set of flash memory banks apparatus includes a memory data path (MDP) module coupled to a test controller. The MDP module includes a test control module configured to generate a concurrent control signal that configures the set of flash memory banks to be tested simultaneously; and a set of comparators, that generates a first comparator output in response to the concurrent control signal and an input from the set of flash memory banks. A reduction logic is configured to generate a reduction logic output that combines a status of the comparator outputs to be compressed. A control logic is configured for selective programming across different flash bits of the set of flash memory banks. A fail flag is configured to generate one of an output value ‘0’ if there is a mismatch in data read from the set of flash memory banks in any access, and an output value 1 if there is no mismatch in data read in any access.
