A memory interface latch including a data NAND gate and a feedback gate can be created within an integrated circuit (IC). When a feedback node is driven low, the data NAND gate can drive an inverted value of a memory array bitline input to a data output of the memory interface latch within a time of one gate delay. A feedback gate can, in a functional mode, during one phase of a clock signal, drive the feedback node high and during the other phase of the clock signal, drive the feedback node to a complement the data output. The feedback gate can be also, in an LBIST write-through mode, drive the feedback node to the value of a WRITE_DATA input. The feedback gate can be also, in a fence mode, drive the feedback node to fixed logic value.
