Abstract
A dual-mode memory is provided that includes a self-timed clock circuit for asserting a sense enable signal for a sense amplifier. In a low-bandwidth read mode, the self-timed clock circuit asserts the sense enable signal only once during a memory clock cycle. The sense amplifier then senses only a single bit from a group of multiplexed columns. In a high-bandwidth read mode, the self-timed clock circuit successively asserts the sense enable signal so that the sense amplifier successively senses bits from the multiplexed columns.
