Abstract
The present application describes embodiments of an interface for coupling flash memory and dynamic random access memory (DRAM) in a processing system. Some embodiments include a dedicated interface between a flash memory and DRAM. The dedicated interface is to provide access to the flash memory in response to instructions received over a DRAM interface between the DRAM and a processing device. Some embodiments of a method include accessing a flash memory via a dedicated interface between the flash memory and a dynamic random access memory (DRAM) in response to an instruction received over a DRAM interface between the DRAM and a processing device.
Claims20
A memory system, comprising:
- a dynamic random access memory (DRAM);
- a flash memory;
- and
- a dedicated interface between the DRAM and the flash memory, wherein a first portion of the dedicated interface is implemented in the DRAM and a second portion of the dedicated interface is implemented in the flash memory, and further wherein the dedicated interface is only available for communication between the flash memory and the DRAM.
A method, comprising:
- accessing a flash memory via a dedicated interface between the flash memory and a dynamic random access memory (DRAM), wherein a first portion of the dedicated interface is implemented in the DRAM and a second portion of the dedicated interface is implemented in the flash memory, and further wherein the dedicated interface is only available for communication between the flash memory and the DRAM.
A memory system, comprising:
- a volatile memory;
- a non-volatile memory;
- and
- a dedicated interface between the volatile memory and the non-volatile memory, wherein a first portion of the dedicated interface is implemented in the volatile memory and a second portion of the dedicated interface is implemented in the non-volatile memory, and further wherein the dedicated interface is only available for communication between the volatile memory and the non-volatile memory.
