Abstract
In a phase change memory, the memory array may be written in relatively small chunks. The writing of data to the array and, particularly, the writing of set data, may be accelerated using a hardware accelerator. The hardware accelerator may include an edge detector which detects a short duration signal pulse to trigger the writing of the set data to a cell. As a result, the writing of data may be accelerated, reducing the time to write in some cases.
Claims38
A method comprising:
- writing to a phase change memory using a software control;
- and accelerating the writing to the phase change memory using a hardware accelerator.
A phase change memory comprising:
- a memory array including phase change memory cells;
- and
- a hardware accelerator configured to accelerate writing data to the phase change memory array.
A system comprising:
- a processor;
- and
- a phase change memory coupled to said processor, said phase change memory including a memory array including phase change memory cells and a hardware accelerator to accelerate writing data to said phase change memory array.
Dependencies are inferred from the claim text.
