Nope. At least if you're talking about parity memory on FPM or EDO DRAM,
which only has a fifty-fifty chance of even noticing an error, and a 1/9
(~11%) chance of reporting an error with the parity bit itself.
Modern SDRAM and DDR memory with ECC will reliably detect and correct
single-bit errors, will reliably detect two-bit errors, and even has a very
good shot (~90+%?) of detecting larger multibit errors.
