Abstract
A clock enable buffer for entry of a self-refresh mode. The clock enable buffer includes a current mirror load connected between a voltage source and first and second nodes, wherein the current mirror load has first and second transistors; a third transistor connected between the first node and a third node, wherein the third transistor is turned on according to a reference voltage; a fourth transistor connected between the second node and the third node, for controlling the current mirror load in response to a clock enable signal; a fifth transistor connected between the third node and a ground, wherein the fifth transistor is turned on according to a self-refresh signal; and a sixth transistor that is turned on according to an inverted self-refresh signal to make the potential of the first node a Low level.
