2.6. Parity Bit in Embedded Memory Blocks

The following describes the parity bit support for M20K blocks:

  • The parity bit is the fifth bit associated with each 4 data bits in data widths of 5, 10, 20, and 40 (bits 4, 9, 14, 19, 24, 29, 34, and 39).
  • In non-parity data widths, the parity bits are skipped during read or write operations.
  • Parity function is not performed on the parity bit.
