Embodiment Construction

[0026] In order to better understand the technical content of the present invention, preferred specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0027] Fig. 2 shows the structural diagram of the SmartMedia / xD-Picture memory card 2 that can use any non-volatile memory of the present invention, and it comprises a card interface 21, a controller 22 and at least one non-volatile memory chip 23, wherein , the card interface 21 is a standard SmartMedia / xD-Picture interface, and the non-volatile memory chip 23 can be various types of flash memory such as NAND, AND, AGAND, or NOR.

[0028] The aforementioned card interface 21 defines commands, data, and address behavior patterns for an external host terminal 29 (such as a portable host terminal or a desktop host terminal) to access the non-volatile memory chip 23 of the memory card 2. For information, in this embodiment, the memory card has N non-volatile memory chips 23 in total....

Abstract

An analog SmartMedia / XD-Picture storage card consists of a non-volatile storage chip (NVSC) a card interface and a controller. It is featured as including control signal and databus defined with command, data and address on card interface to let external host make access of data on NVSC; using the controller to translate command of host end, to convert address sent by host to be effective address acceptable by NVSC for carrying out data Write-in, fetch or delete for addressed NVSC.

Description

technical field [0001] The present invention relates to a memory card device, especially an analog SmartMedia / xD-PictuTe memory card that can use any non-volatile memory. Background technique [0002] With the hot sales of portable electronic products such as digital cameras and PDAs, and the rise of the concept of IA, consumers' demand for accessing data anytime and anywhere is increasing day by day, which also stimulates the rapid growth of the small flash memory card market. Today, flash memory cards It is the only storage media solution for these thin, light, portable precision electronic devices. Figure 1 shows the structure of a SmartMedia / xD-Picture Card flash memory card, which directly integrates the anti-and-type flash memory (NAND Flash) chip 11 is packaged, and the pin signal of the flash memory chip 11 is used as the interface signal of the card. As for the file management, it is directly controlled by the software on the host side, so it has the advantages of s...
