UT54ACS630 Datasheet (Aeroflex Circuit Technology)

UT54ACS630, RadHard EDAC

The UT54ACS630 is a RadHard 16-bit parallel error detection and correction circuit.

It uses a modified Hamming code to generate a 6-bit checkword from each 16-bit data word.

The checkword is stored with the data word during a memory write cycle; during a memory read cycle a 22-bit word is taken from
