Abstract
A circuit and method efficiently provide detection of corruption of data using an error correcting code (ECC). The circuit includes an ECC checker, a memory arrangement, and a detection circuit. The ECC checker generates a remainder of an ECC check of the data and an ECC value generated from an uncorrupted version of the data. The memory stores a set of values and receives a first portion of the remainder at a first address port and a second portion of the remainder at a second address port. The memory arrangement outputs a first value of the set responsive to a value of the first portion and output a second value of the set responsive to a value of the second portion. The detection circuit generates an error indication in response to the first and second values to indicate whether a single bit of the data is incorrect.
