Talk about the performance index of memory
There are four performance indicators for evaluating memory modules:
(1) Storage capacity: that is, the binary information that can be held by a memory bar, such as the storage capacity of the commonly used 168-line memory bar is generally 32 megabytes, 64 megabytes and 128 megabytes. DDRII3 is generally 1GB to 8GB.
(2) Access speed (storage cycle) : that is, the shortest time required between two independent access operations, also known as the storage cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.
(3) Reliability of memory: The reliability of memory is measured by the average time between failures, which can be understood as the average time interval between two failures.
(4) Price/performance: Performance mainly includes memory capacity, storage cycle and reliability three content, the price/performance is a comprehensive index, for different memory has different requirements.
