Abstract

The present invention provides a semiconductor memory device capable of writing data into a memory area and reading data from the memory area, wherein the semiconductor memory device has a circuit for switching sequences of unit data comprising plural bytes to be consecutively transmitted as a unit for at least one of data write or read operations, so that, in accordance with a designated address of a memory area, a corresponding datum of the unit data to the designated address is first transmitted, followed by a consecutive transmission of remaining data in a predetermined basic cyclic sequence, whereby if any address of the memory area is designated, then the unit data comprising the plural bytes are consecutively transmitted as a unit without intervening any operation of switching word lines connected to the memory area.
