Abstract
A wireless device to include a non-volatile memory to execute an encoding scheme to provide single-cell error detection and correction on program operations in which the initial nibble value is Fh and on program operations that result in a nibble value of 0h. The non-volatile memory uses multiple writes to program a nibble more than once with non-zero data between erase cycles.
Claims20
A wireless device, comprising:
- a multicore processor;
- and
- a non-volatile memory device coupled to the multicore processor and having an encoder controller to provide first write error protection to a four-bit boundary.
A wireless device, comprising:
- a multicore processor;
- and
- a non-volatile memory device coupled to the multicore processor and having an encoder controller to program a nibble more than once with non-zero data between erase cycles.
A method to dynamically encode a memory device connected to a processor, comprising:
- using an encoder controller within the memory device to execute an encoding scheme where sixteen first-write nibble codes are orthogonal codes.
