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.
• The vast majority of power used in DRAM is used for refresh, so it seems reasonable to suggest that the benchmark quoted by TTR-MRAM researchers is useful here too, indicating power usage about 99 % lower than DRAM . The destructive read aspect of FeRAM may put it at a disadvantage compared to MRAM, however.
