Abstract
A semiconductor memory device is provided for simultaneously reading data of a plurality of bits from its memory cell region and outputting the data successively to an external environment, and includes: an external output section whose output state to the external environment is altered for one output logical level and not altered for another output logical level; a output level generation section for assigning a logical level corresponding to the content of bit-data to a bit freely selected out of the data, and assigning another output logical level to another bit; and a supply section for successively supplying the output logical levels, generated by the output level generation section to correspond with respective bits of the data, to the external output section.

A semiconductor memory device for reading data of a plurality of bits from its memory cell region simultaneously and outputting said data to an external environment successively, including:
- external output means whose output state to the external environment is altered for one output logical level and not altered for another output logical level;
- output level generation means for assigning a logical level corresponding to the content of bit-data to a bit freely selected out of said data, and assigning said another output logical level to another bit;
- and
- supply means for successively supplying the output logical levels, generated by said output level generation means to correspond with respective bits of said data, to said external output means.
