STORAGE DEVICE AND COMPUTER DEVICE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18342252 Titled 'STORAGE DEVICE AND COMPUTER DEVICE'
Simplified Explanation
This abstract describes a storage device and a computer device in the field of computer technologies. The storage device includes a first PCM (Phase Change Memory), a main memory, and a controller. The first PCM and the controller are packaged together in a single chip. The first PCM has a lower latency (faster access time) compared to the main memory, but the main memory has a higher storage density (can store more data). The controller is designed to store data in both the first PCM and the main memory based on the read/write temperature of the data. The first PCM acts as a cache for the main memory. The main advantages of this design are increased cache capacity and reduced device costs.
Original Abstract Submitted
Embodiments of this application disclose a storage device and a computer device, and belong to the field of computer technologies. The storage device includes a first PCM, a main memory, and a controller. The first PCM and the controller are packaged in a same chip. A latency of the first PCM is less than that of the main memory, and storage density of the main memory is greater than that of the first PCM. The controller is configured to store data in the first PCM and the main memory based on a read/write temperature of the data, where the first PCM is a cache of the main memory. According to embodiments of this application, a cache capacity of the storage device can be increased, and device costs can be reduced.
