Abstract
A method, apparatus and system providing a memory device having an array of cells which may be selectively designated for either error correction code use or redundancy cell use.
Claims32
A memory device, comprising:
- an array of memory cells, said array partitioned into at least an error correction code area, a user-accessible memory area, a redundancy cell area, and an additional area which can be configured as an additional error correction code area or an additional redundancy area;
- and
- a multiplexer for receiving a first input, a second input, and a settable select input, said multiplexer being controlled to output a signal from said first or second inputs to said additional area.
A system comprising:
- a processor;
- a non-volatile memory device coupled to said processor, said non-volatile memory device comprising:
- an array of non-volatile memory cells comprising a plurality of memory cells arranged in rows and columns, said array partitioned into at least a user-accessible memory area, an error correction code area, a redundancy cell area, and an additional area which can be configured as an additional error correction code area or an additional redundancy cell area;
- and
- a multiplexer for receiving a first input, a second input, and a settable select input, said multiplexer being controlled to output a signal from said first or second inputs to said additional area.
A method of operating a memory device having a memory cell array comprising a user-accessible memory area, an error correction code area, a redundancy cell area, an additional area, and the memory device further comprising a multiplexer for receiving a first input, a second input, and a settable select input, said method comprising the act of designating the additional area for use as either an additional error correction code area or an additional redundancy cell area.
