Abstract
A system for measuring an access time of a memory includes a first delay unit configured to delay a clock signal by a first delay time and to output a first delayed clock signal, a second delay unit configured to delay the clock signal by a second delay time greater than the first delay time and to output a second delayed clock signal, a memory configured to store data, the data being read from the memory in response to the first delayed clock signal, a detection data storage configured to store the data read from the memory in response to the second delayed clock signal, and a controller configured to measure an access time of the memory based on a comparison of the data in the detection data storage and the data in the memory, the first delayed clock signal and the second delayed clock signal.
