Abstract
A memory system that splits a data width (W) into N separate memories each of narrower width W/N is described. To protect a write enable (WE) signal, the WE signal is toggled and then stored in each of the N memories. A fault on the WE signal to any of the N memories results in its stored write detection bit being different from the write detection bits stored in the other N memories. This condition can then be detected upon any subsequent read by checking whether the write detection bits are equal. The memory system can also protect the address and control signals by generating parity bits that are stored in the N memories.
