Answer:
Column Access Strobe (CAS) latency
Explanation:
Column Access Strobe (CAS) latency is the time limit between the READ command and the time when information is accessible.
The interval is defined in nanoseconds in asynchronous DRAM(Dynamic random-access memory).The interval is defined in clock cycles in synchronous DRAM.
Since latency depends on a number of clock ticks rather than absolute time, if the clock rate differs, the actual time for a SDRAM (Synchronous dynamic random-access memory) module to respond to a CAS event may vary.
