Classification: G11C,H03K

Abstract:
An input buffer, comprising:a controllable input stage connected to receive an external input signal, the controllable input stage operable to sense the rising edge of the external input signal and generate an output signal at an output of the controllable input stage in response thereto;a driver circuit having an input and an output, the input of the driver circuit coupled to the output of the controllable input stage, the driver circuit generating a rising edge of an internal signal at its output in response to the output signal of the controllable input stage generated in response to the rising edge of the external input signal; anda delay circuit coupled to the driver circuit, the delay circuit receiving the rising edge of the internal signal, and generating a signal that causes the driver circuit to generate a falling edge of the internal signal independent of the falling edge of the external input signal.
