There is provided a serial access memory and a data write/read method applicable thereto. The serial access memory is able to function as the prior art FIFO type serial access memory and as the prior art line access type serial access memory, too. This serial access memory 101 is provided with a memory cell array 11, a write register group 17, a read register group 20, and a write/read register group 32. The write/read register group 32 is made up of write/read registers WRreg-1 to WRreg-m. These write/read registers are prepared by the same number as that of memory cells (m pieces) connected with each of word lines WL1 to WLn, in the same way as the write registers Wreg-1 to Wreg-m forming the write register group 17 and the read registers Rreg-1 to Rreg-m forming the read register group 20.
