29C516E 16 Bit Flow Through EDAC Error Detection And Correction unit 1. Introduction The 29C516E Atmel EDAC is a very low power flow through 16 bit Error Detection And Correction unit (EDAC) with two user data buses. The EDAC is used in a high integrity system for monitoring and correction of data values coming from the memory space. During a processor write cycle, at each memory location (16 bit width), EDAC calculated checkword (6 or 8 bit width).
