Abstract
A technique includes, in response to a request to write data to memory cells of a phase change memory device, placing the memory cells in a state that is shared in common among the memory cells. Also, in response to this request, the data is written to the memory cells.
Claims40
A method comprising:
- in response to a request to write data to memory cells of a phase change memory device, placing the memory cells in a state shared in common among the memory cells;
- and
- in response to the request, writing the data to the memory cells.
A memory controller comprising:
- a first circuit to receive data associated with a request to write data to a group of at least one memory cell of a phase change memory device;
- and
- a second circuit to:
- in response to the request, place each memory cell in the group in a state shared in common among said at least one memory cell of the group, and
- in response to the request, perform a write operation to the phase change memory device to cause said at least one memory cell to indicate the data.

A computer system comprising:
- a phase change memory;
- and
- a memory controller to:
- receive data associated with a request to write data to a group of at least one memory cell of the phase change memory device,
- in response to the request, place each memory cell in the group in a state shared in common among said at least one memory cell of the group, and
- in response to the request, perform a write operation to the phase change memory device to cause said at least one memory cell to indicate the data.

A memory device comprising:
- an array of phase change material-based memory cells;
- a first circuit to receive data associated with a request to write data to a group of the memory cells;
- and
- a second circuit to:
- in response to the request, place each memory cell in the group in a state shared in common among the memory cells of the group, and
- in response to the request, write the data to the phase change memory device.
3 more elements
A computer system comprising:
- a memory controller to provide signals indicative of a write operation;
- and
- a phase change memory to:
- in response to the signals, place each memory cell in a group of cells targeted by the write operation in a state shared in common among the memory cells of the group, and
- perform at least one write cycle to cause the memory cells of the group to indicate the data.
