SK0-003 Question #818: Real Exam Question with Answer & Explanation
The correct answer is D. The number of clock cycles to return a request. CAS latency, or Column Access Strobe latency, is a critical memory timing specification that indicates the delay in clock cycles between a data request and when the data becomes available.
Server hardware installation and management
Question
Which of the following is the CAS latency of a memory module?
Options
- AThe number of clock cycles to verify the data
- BThe number of clock cycles to store data
- CThe number of clock cycles to clear the module
- DThe number of clock cycles to return a request
Explanation
CAS latency, or Column Access Strobe latency, is a critical memory timing specification that indicates the delay in clock cycles between a data request and when the data becomes available.
Common mistakes.
- A. CAS latency is not related to verifying data integrity; it specifically quantifies the time taken to access and retrieve data.
- B. CAS latency describes the delay in reading or returning data, not the time it takes to store data in the memory module.
- C. CAS latency is a read-related timing parameter and has no direct relation to clearing or resetting the memory module.
