Question

What are the two different ways of measuring access timing for memory?

1) CAS Latency
2) NS Latency
3) RAS Latency
4) None of the above

Answer 1

Memory access timing can be measured using CAS Latency and RAS Latency, where CAS measures the delay between the memory controller's command and data availability, and RAS measures the time to activate a row. NS Latency is a general time measure and not a separate type of memory latency.

Step-by-step explanation:

There are two different ways of measuring access timing for memory: CAS Latency and RAS Latency. CAS (Column Address Strobe) Latency measures the time it takes between when a memory controller tells the memory module to access a particular memory column on a RAM module and when the data from that column is available for use. On the other hand, RAS (Row Address Strobe) Latency is the time it takes between the memory controller initiating an action and the row of the memory being activated for that action. NS Latency, which stands for nanoseconds latency, is not a specific type of latency measure but rather a general measure of time; it could refer to how long any given operation takes but is not itself a distinct method for measuring memory access time alongside CAS and RAS.
