Product overview

The UT54ACS630 is a parallel error-detection and correction circuit for 16-bit data words. It generates a six-bit check word using a modified Hamming code, stores that check word with the data, and evaluates the resulting 22-bit word during a read. Single-bit errors in data are flagged and corrected; errors in check bits are flagged but not corrected. A six-bit syndrome identifies the incorrect bit. Bidirectional data and check-bit buses support the encode and check operations, while dedicated error outputs report detected conditions.

Memory-word error checking

It generates a six-bit check word using a modified Hamming code, stores that check word with the data, and evaluates the resulting 22-bit word during a read. Single-bit errors in data are flagged and corrected; errors in check bits are flagged but not corrected. A six-bit syndrome identifies the incorrect bit.
