Abstract
A semiconductor memory device includes: static memory cells arranged in a matrix; a read bit line for transmitting data read from one of the memory cells; a write bit line for transmitting data to be written to one of the memory cells; an input data line for transmitting data which is received from outside and is to be written in one of the memory cells; and a selector for selectively transmitting data of the read line or the input data line to the write bit line.
Claims8
A semiconductor memory device comprising:
- static memory cells arranged in a matrix;
- a read bit line for transmitting data read from one of the memory cells;
- a write bit line for transmitting data to be written to one of the memory cells;
- an input data line for transmitting data which is received from outside of the static memory cells;
- and
- a selector physically connected to the read bit line, the write bit line, and the input data line, wherein
- the selector receives a column select signal,
- the selector selects one of the read bit line and the input data line according to the column select signal, and
- the selector electrically connects the selected one to the write bit line.
