There are many measures of memory access. They vary in speed the fastest being magnetic tapes. That may not be a popular choice in this technological age. The next fastest would be magnetic disks, followed by Semiconductor memories and then compact disks.

The fastest way to measure memory access time in computers is by using specialized benchmarking tools that directly test memory read and write speeds, such as AIDA64 or MemTest86. These tools typically utilize low-level operations to minimize overhead and provide accurate measurements. Additionally, performance counters available in modern CPUs can be leveraged to measure memory latency with high precision by analyzing specific instructions and their execution times.
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
Memory device operating speed is measured in cycle time which is the amount of time required for memory to perform read and write operation and return to its original state ready for next operaiton. Access time is another measure of memory speed which is only the time required for read operation or it is the time between data receiving (read operation) and the data becoming available at the memory output.

cache memory
Memory access time can be calculated using the formula: Memory Access Time = Hit Time + (Miss Rate × Miss Penalty). Here, the hit time is the time taken to access data from cache when it is found, while the miss rate is the frequency of cache misses. The miss penalty is the time required to retrieve data from the main memory when it is not available in the cache. By combining these factors, you can estimate the overall memory access time.
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
it is defined by access time and cycle time
