Abstract
Disclosed embodiments include an electronic device having a write-once memory (WOM) and a memory controller. The memory controller includes a host interface receiving a data word including first and second symbols, each having at least two bits, a WOM controller that encodes the first and second symbols and outputs a WOM-encoded word including first and second WOM codes corresponding to the first and second symbols, respectively, an error correction code (ECC) controller that encodes the WOM-encoded word and outputs an ECC-encoded word including the first and second WOM codes and a first set of ECC bits corresponding to a first write operation, and a memory device interface that writes the ECC-encoded word the WOM device in the first write operation. Each of the first and second WOM codes include at least three bits with at least two of the at least three bits having the same logic value.
