Quick flashing memory device with characteristic commutation function

Abstract

The invention is a quick flashing memory device with characteristic shifting function which is provided with a first characteristic. The quick flashing memory device comprises a quick flashing memory unit with a second characteristic, a characteristic shifting unit for shifting the characteristic between the first and second characteristic to make a main machine access the quick flashing memory cell according to the first characteristic. In this way, the device can shift characteristic for quick flashing memory cell with different characteristic to make the circumscribed main machine access quick flashing memory cell without changing hardware design and have no compatibility problem.

Description

technical field [0001] The invention relates to a flash memory, in particular to a flash memory device with a characteristic conversion function. Background technique [0002] In recent years, flash memory has become the memory medium used by most portable memory devices. Such as USB flash disk (USB Flash Disk, commonly known as silicon disk drive or thumb brother), and including small size flash memory (Compact Flash, CF), memory stick (Memory Stick, MS), secure digital (Secure Digital, SD), multimedia card (Multi Media Card, MMC) and other specifications of flash memory card (flash memory card), using CF or USB interface micro hard disk (micro hard disk), or using USB or PCMCIA interface and installed in an external box Thin 2.5-inch hard disk drive, etc., to meet the modern people's desire for "information portability" and the ever-increasing desire. In addition, in many portable electronic devices using embedded memory, such as MP3 players popular in recent years, most...

Problems solved by technology

However, for manufacturers of portable devices, the characteristics of the new generation of flash memory (such as pin definition, operating voltage, etc.) , the relevant hardware circuit needs to be redesigned

In addition, different brands of flash memory often have different characteristics, which will also cause manufacturers to redesign related hardware when they want to use other brands of flash memory.

This phenomenon of redesigning the circuit due to upgrading the flash memory or changing the brand name will delay the design-in cycle of the manufacturer, increase the manufacturing cost, and may lose market opportunities due to delays in production.
