A serial access memory comprises a data transfer unit including a memory cell array (101) having a plurality of memory cells arranged therein for storing data, a first transfer register (117) electrically connected to the memory cell array through a first switching circuit (115) and a second transfer register (127) electrically connected to the first transfer register through a second switching circuit (125). When each of the first and second switching circuits (115, 125) is in an ON state, data passes through the first transfer register (117) so as to be transferred from the memory cell array (101) to the second transfer register (127), and when the first switching circuit is in an ON state and the second switching circuit is in an OFF state, data is transferred from the memory cell array to the first transfer register. |
