Abstract
With a serial interface memory device of this invention, a read-out rate of data is increased, while an increase in a size of a circuit is suppressed. An EEPROM is provided with a memory cell array storing data, a row address decoder and a column address decoder that select an address of the memory cell array in accordance with an address signal serially inputted in synchronization with a clock, sense amplifiers SA-SA, SA_Mand SA_Meach provided corresponding to each bit of the data, and a shift register that outputs the data read out from the sense amplifiers serially from a first bit. The column address decoder commences reading out two candidate data for the first bit by inputting each of the two candidate data to each of the two sense amplifiers SA_Mand SA_M, respectively, before all bits of the column address signal are established.
