Abstract
A synchronous memory device is provided in which the cycle time is shorter than conventional memory devices. For example, by providing an output latch in a sense amplifier on a bit line, the time period from input of a clock signal to latching data in the output latch is shortened. In case of plural bit lines, a selector for selecting data in a plural output latch and a latch for latching a sense amplifier selection are provided.
