Data processing method in large capacity quick electric erasing and writing programmable read-only memory system

Abstract

The present invention relates to a device that is equipped with access to at least one fast electrically erasable programmable read-only memory and a host computer to access the host computer, and download data in the data area of ​​the fast electrically erasable programmable read-only memory EEPROM systems for controllers that interface with any data required, in particular, if provided to set the data area of ​​said EEPROMs to a given arbitrary specification The first process of dividing a predetermined number of information packet areas and subdividing each information packet area with a predetermined number of mapping table areas; using sequence blocks, physical blocks and physical blocks stored in the volatile memory area inside the controller The look-up table of the spare block is used as a reference, and the data area of ​​the fast electrically erasable programmable read-only memory to be accessed by the host computer is provided by the second process in the unit of the mapping table area subdivided in the first process The data operation method of the large-capacity fast electrically erasable programmable read-only memory, which will reflect the use of large-capacity fast electrically erasable programmable read-only When running such a block, the effect can be run even if the number of packets exceeds the volatile memory.

Description

technical field [0001] The present invention relates to a storage device area using a fast electrically erasable programmable read-only memory, that is, a system of a fast electrically erasable programmable read-only memory that stores data in devices such as computers and digital cameras. In particular, it relates to a supplementary recording device using a fast electrically erasable programmable read-only memory with limited volatile memory capacity, and a lookup table required for running the information block of the fast electrically erasable programmable read-only memory required for accessing data files If the volatile memory is exceeded, the data operation method of the large-capacity fast electrically erasable programmable read-only memory required for running the table will be separated. Background technique [0002] Recently, fast electrically erasable programmable read-only memory is increasingly favored by people as a semiconductor memory replacing hard disks, fl...

Problems solved by technology

Therefore, when using a limited-capacity volatile memory, the number of information blocks that should be processed in real time according to the situation will exceed the capacity of the volatile memory. At this time, there will be disadvantages such as difficulty in processing actual data or errors.
