Abstract
A low power consumption semiconductor memory device that can read stored data at a faster access time, while minimizing power consumption is provided. In accordance with the logic states on a pair of bit lines on which an information signal stored in the memory cell and an inverted version of that information signal are placed, it is detected that the information signal is placed onto the bit line, and then the information signal on that bit line is read onto the data signal bus.
Claims4
A low power consumption semiconductor memory device comprising:
- a memory cell where an information signal is stored;
- a pair of bit lines on which the information signal stored in said memory cell and an inverted version of said information signal are placed;
- an information signal sense means for detecting when said information signal is placed onto said bit line in accordance with the exclusive-OR logic value of each of said bit lines and generating an information sense signal;
- and
- an information signal reading means, responsive to said information sense signal, for reading said information signal on said bit line onto a data signal bus.
