Abstract
The technology described herein includes a first plurality of bijection diffusion function circuits to diffuse data bits into diffused data bits and store the diffused data bits into a memory; an error correcting code (ECC) generation circuit to generate ECC bits for the data bits; and a second plurality of bijection diffusion function circuits to diffuse the ECC bits into diffused ECC bits and store the diffused ECC bits into the memory.
