Virtual memory device including a bridge circuit

Abstract

A virtual memory device includes a bridge circuit wherein in an integrated SOC device, a bridge circuit with less than 10% die size and a non-volatile XIP random access memory is used to connect to a high efficiency memory bridge circuit, so as to facilitate an improvement of boot-up speed and MMI initialization of a portable mobile device, and performance of network searching and network protocol of a wireless station, as well as a reduction of cost of the entire memory, upon applying inside the portable wireless mobile device. The invention includes an integrated SOC application system interface, incorporating a NAND flash memory, an XIP non-volatile random access memory, a programmable MIF bridge, and a volatile XIP random access memory, is used to perform a virtual memory without an MCU system control interface being a new architecture of MCU system control interface, by means of software simulation.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a virtual memory device including a bridge circuit, and more particularly to a virtual memory device wherein a bridge circuit with less than 10% die size and a non-volatile XIP (Execute In Place) random access memory is used in an integrated SOC (System-On-Chip) device to connect to a high efficiency memory bridge circuit, thereby constituting a new architecture of virtual memory device. [0003] (b) Description of the Prior Art [0004] As the continuous advancement of existing personal digital products, their functions are also becoming more versatile. Therefore, a memory device of portable application architecture is also becoming more sophisticated under a restriction of size. However, storage space in a virtual memory is becoming to fail in meeting requirements. The major reason is that the virtual memory with higher efficiency requires the memory with higher storage space for stor...

Benefits of technology

[0006] The present invention is to provide a virtual memory device including a bridge circuit, wherein a bridge circuit with less than 10% die size and a non-volatile XIP random access memory is used in an integrated SOC device to connect to a high efficiency memory bridge circuit, so as to facilitate an improvement of boot-up speed and MMI (Man-Machine Interface) initialization of a portable mobile device, and performance of network searching and network protocol of a wireless station, as well as a reduction of cost of the entire memory, upon applying the new architecture of virtual memory device inside the portable mobile device.

Problems solved by technology

However, storage space in a virtual memory is becoming to fail in meeting requirements.

Therefore, if portable application architecture with a small size and high price is used, a better solution to the storage space in its virtual memory is still not available.
