False Parity Memory

A third type of parity memory that exists that does not in fact perform any parity checking or correction. False Parity Memory (a.k.a. Logic Memory) was designed to replace parity memory in systems where parity mode was unable to be turned off in the BIOS. In essence what it did was to fake out the BIOS into thinking that it was talking to true parity memory. What was the point of this? The special logic circuit used in place of the ninth chip in parity memory was a few cents cheaper.
