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...
