Abstract
A memory system, memory, and memory system command protocol are disclosed. Within the memory system, a memory controller communicates a command to the memory, the command being selected from a set of commands including a write command and a plurality of non-write commands. A Hamming distance value calculated between a digital value indicating the write command and a digital value indicating any one of the plurality of non-write commands is greater than 1.
Claims32
A memory system comprising:
- a memory controller communicating a command to a memory, the command being selected from a set of all commands that are executable within the memory system, wherein the set of all commands includes a plurality of write commands and a plurality of non-write commands, and a Hamming distance value calculated between a respective digital value indicating each and every one of the plurality of write commands in the set of all commands and a respective digital value indicating each and every one of the plurality of non-write commands in the set of all commands is greater than 1.
A memory system comprising:
- a memory controller connected to a plurality of memory elements arranged on a memory card via a plurality of point-to-point interfaces;
- the memory controller communicating a command to at least one memory associated with at least one of the plurality of memory elements, the command being selected from a set of all commands that are executable within the memory system, wherein the set of all commands includes a plurality of write commands and a plurality of non-write commands, and a Hamming distance value calculated between a respective digital value indicating each and every one of the plurality of write commands in the set of all commands and a respective digital value indicating each and every one of the plurality of non-write commands in the set of all commands is greater than 1.
A method controlling operation of a memory within a memory system, the method comprising:
- selecting a command from a set of all commands that are executable within the memory system, the set of all commands comprising a plurality of write commands and a plurality of non-write commands, and
- communicating the selected command to the memory, wherein a Hamming distance value calculated between a respective digital value indicating each and every one of the plurality of write commands in the set of all commands and a respective digital value indicating each and every one of the plurality of non-write commands in the set of all commands is greater than 1.
