destructive read การใช้

The 9000 series used plated wire memory, which functioned somewhat like core memory but used a non-destructive read.
Operation was generally similar to core, but could also be built with a non-destructive read that did not require refreshing.
As a consequence, the memory controller typically added a refresh cycle after each read cycle in order to create the illusion of a non-destructive read operation.
This illustrates why a core memory access is called a " destructive read " : Any operation that reads the contents of a core erases those contents, and they must immediately be recreated.
Phase-change memory has many near ideal memory qualities such as non-volatility, fast switching speed, high endurance of more than 10 13 read write cycles, non-destructive read, direct overwriting and long data retention time of more than 10 years.
