Abstract
A switch signal generator simultaneously sets every input and output data path in a high-speed synchronous SRAM. The switch signal generator receives control signals and a plurality of input signals, generates a plurality of switch signals, and sequentially enables other switch signals when a first switch signal of the plurality of switch signals is enabled. The synchronous SRAM includes an output data path/data storing portion, an input data path/data storing portion, and a path switch controlling portion. All burst orders are set simultaneously in the path switch controlling portion including the switch signal generator when a burst operation starts, and all data paths of the output data path/data storing portion and the input data path/data storing portion are simultaneously set by switch control signals which are provided by the path switch controlling portion.
