Semiconductor storage device |
摘要 |
The semiconductor storage device has a clock input buffer to output an internal clock signal INCLK, a NOT circuit to receive an external signal /CS, and an OR circuit to receive the output of the NOT circuit and a refresh request signal RFR and output their logical sum as an internal clock enable signal INCE to the clock input buffer. The clock input buffer has a NAND circuit to receive a clock signal CLK and the internal clock enable signal INCE and output an inverted signal of their logical product.
