Embodiment Construction

[0010] The various names may refer to components or systems. A system may be a subsystem of another system. If a first device couples to a second device, that connection may be through a direct electrical connection or through an indirect electrical connection via other devices and connections.

[0011] figure 1 An illustrative computing system 100 is shown in accordance with an example embodiment. For example, computing system 100 is or is incorporated into electronic system 129, such as a computer, an electronic control "box" or display, a communication device (including a transmitter), or any other type of electronic system arranged to generate radio frequency signals.

[0012] In some embodiments, computing system 100 includes a megacell or system on a chip (SoC) that includes control logic such as CPU 112 (central processing unit), storage 114 such as random access memory (RAM), and power supply 110. For example, the CPU 112 may be a CISC type (Complex Instruction Set ...

Abstract

In described examples, a system for error correction code (ECC) management of write-once memory (WOM) codes includes a host processor arranged to send a data word that is to be stored in a WOM (write-only memory) device. A host interface is arranged to receive (710) the first data word for processing by a WOM controller and an ECC controller. The WOM controller is for generating (720) a first WOM-encoded word in response to an original symbol of the first data word, while the ECC controller is for generating (730) a first set of ECC bits in response to the original symbol of the first data word. A memory device interface is for writing (740) the first WOM-encoded word and the first set of ECC bits to the WOM device in accordance with the memory address associated with the first data word.

Description

Background technique [0001] The computer system includes a processor operable to retrieve, process and store data in memory devices. Memory devices for computer systems include different types of memory devices, where different types of memory devices typically have different performance and operating characteristics. The type of memory device used in a particular system is generally selected according to the requirements of the particular application of the computer system. For example, some system designs require the ability to write data to and read data from nonvolatile memory locations. However, some memory device solutions, such as electrically erasable read-only memory, are not suitable for certain applications due to increased cost and reduced performance characteristics. Contents of the invention [0002] The problems noted above can be addressed by the described example of a system for error correction code (ECC) management of write-once memory (WOM) codes. In t...
