Neither Crucial nor Micron Technology, Inc. is responsible for omissions or errors in typography or photography. A picosecond (abbreviated as ps) is a unit of time in the International System of Units (SI) equal to 10 12 or 11 000 000 000 000 (one trillionth) of a second. To calculate a module's latency, multiply clock cycle duration by the total number of clock cycles. I know that 10 years ago, typical clock precision equaled a system-tick, which was in the range of 10-30ms. In the history of memory technology, as speeds have increased, (which means clock cycle times have decreased),the CAS latency values have also increased, however because of the faster clock cycle the true latency as measured in nanoseconds has remained roughly the same. Here's what these calculations look like. How is it possible to measure in nanoseconds? At Clarity, we frequently hear a continued question of "why does it take so long" to retrieve data from the server, the internet, and my computer?
