Abstract
A memory which is cleared by simultaneously clearing a special bit in each entry within the memory, an extra bit, used for other purposes, is also cleared. When both bits have a value of 0, parity checking is disabled. When either bit has a value of 1, parity checking is enabled. This prevents incorrect detection of parity errors after the memory device has been cleared.
