Abstract
In some aspects of the present disclosure, a memory device is disclosed. In some aspects, the memory device includes a plurality of memory cells arranged in an array, an input/output (I/O) interface connected to the plurality of memory cells to output data signal from each memory cell, and a control circuit. In some embodiments, the control circuit includes a first clock generator to generate a first clock signal and a second clock signal according to an input clock signal and a chip enable (CE) signal and provide the first clock signal to the plurality of memory cells. In some embodiments, the control circuit includes a second clock generator to generate a third clock signal according to the input clock signal and a DFT (design for testability) enable signal. In some embodiments, the control circuit generates an output clock signal according to the second clock signal or the third clock signal.
