A memory request does not simply point at a byte and receive it at a fixed cost. Inside each bank, the device first brings an entire row into sense amplifiers that also act as a row buffer. Column commands then select data from that active row.</p> <p>This organization creates a practical timing difference between accesses that stay on the active row and accesses that require a different row.</p>
