An SRAM multiplexing apparatus comprise a plurality of local multiplexers and a global multiplexer. Each local multiplexer is coupled to a memory bank. The global multiplexer has a plurality of inputs, each of which is coupled to a corresponding output of the plurality of local multiplexers. In response to a decoded address in a read operation, an input of a local multiplexer is forwarded to a corresponding input of the global multiplexer. Similarly, the decoded address allows the global multiplexer to forward the input signal to a data out port via a buffer.
