29C516E中文资料16–Bit Flow–Through EDAC Error Detection And Correction unit数据手册Microchip规格书

描述 Description

Introduction
The 29C516E AtmelEDAC is a very low power flow–through16–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) is added. When performing a read operation from memory, the 29C516E verifies the entire checkword and data combination. It detects and can correct 100% of all the single–bit errors and it detects all double–bit errors.
