Abstract:
A bypass system and method that mimics read timing of a memory system which includes a self-timing circuit and a sense amplifier. When prompted, the self-timing circuit initiates the sense amplifier to evaluate its differential input. The bypass system includes a memory controller that is configured to provide a bypass enable, to prompt the self-timing circuit, and to disable normal read control when a bypass read operation is indicated. A bypass latch latches an input data value, converts the input data value into an input complementary pair, and provides the complementary pair to the differential input of the sense amplifier. The sense amplifier, when initiated, evaluates the input complementary pair after its self-timing period and provides an output data value. The bypass latch and self-timing circuit may operate synchronous with a read clock in a read domain of the memory for more accurate memory read timing.
