Non-Parity, Parity and ECC Memory

Parity memory can be used for parity checking, a basic form of error detection, on PCs that support it.

It can also be used for an advanced form of error detection and correction called ECC on Pentium class or later systems that support ECC.

Non-parity memory provides no error detection capabilities at all unless these are provided through external circuitry (which is basically never done on regular PCs.)

parity check memory 可以執行 ECC 或是 parity check 這兩種偵錯模式
ECC memory 只能執行 ECC 但是無法執行 parity check 偵錯模式
