Abstract
Official abstract text for this publication.
A system for programming a phase change material-content addressable memory (PCM-CAM). The system includes a receiving unit for receiving a word to be written in the PCM-CAM. The word includes low bits represented by a low resistance state in the PCM-CAM and high bits represented by a high resistance state in the PCM-CAM. The system includes a writing unit configured to repeatedly write the low bits in memory cells of the PCM-CAM until the resistance of the memory cells are below a threshold value, and to write high bits in memory cells of the PCM-CAM only once.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for programming a Phase Change Material-Content Addressable Memory (PCM-CAM) comprising: a receiving unit for receiving a word to be written in a PCM-CAM, the word including low bits represented by a low resistance state in the PCM-CAM and high bits represented by a high resistance state in the PCM-CAM; and a writing unit configured to repeatedly write the low bits in memory cells of the CAM-PCM until the resistance of the memory cells are below a…
