Abstract
In a serial memory, data signal holding circuits for temporarily holding data read from memory cells are provided as a data register. One holding circuit includes a latch circuit and capacitors connected to input/output nodes of the latch circuit, respectively. The capacitors contribute to stabilizing the latch function by the latch circuit. Therefore, when transistors turn on in response to a serial selection signal at a high level, the latch circuit is prevented from being inverted by the potentials of a serial bus line pair. Accordingly, generation of reading errors is prevented.
