Problems solved by technology

It only needs to use a very low data space for storing the corresponding error correction check code, and the flash memory data space is more efficient", but it is not convenient for the device to disassemble the cable;
[0005] 2. Patent document CN112100095A discloses a flash memory space optimization method, device and flash memory storage device. The protected right is "used in the field of information storage. The cache space is divided into a data cache area and a mapping table cache area. The optimization method includes; Obtaining an I / O command, and judging the data length of the I / O command; if the I / O command is a short I / O command with a data length less than a predetermined data threshold X, and the obtained short I / O command When the cumulative quantity is greater than the predetermined quantity threshold Y, the expansion mode is turned on; when the expansion mode is enabled, the dynamic cache partition preset in the data buffer area is allocated to the mapping table buffer area for the mapping table buffer area Expand and cache the data area of ​​the flash memory space associated with the new physical address, and execute a large number of short I / O commands; in the application scenario of random short I / O, effectively use the space in the data cache area to expand the original mapping table space, Due to the short data length of the application scenario of random short I / O, the space is provided for the use of the mapping table", but the heat dissipation structure of the device cannot be adjusted, which is not flexible enough;
This application can reduce the use of memory while taking into account the data recovery ability, thereby reducing the cost of implementing redundant computing", but its device lacks a warning structure, and cannot warn in time when a problem occurs

Abstract

The invention discloses a flash memory storage device based on cold and hot data analysis technology, the flash memory storage device comprises a main body, a heat dissipation frame, a circulator, a mounting hole and a warning indicator, the top of the main body is provided with a connecting hole, the inner wall of the main body is provided with a rotating shaft, the front side of the main body is provided with the heat dissipation frame, the top of the heat dissipation frame is provided with a temperature detector, and the temperature detector is provided with a temperature sensor. And a warning indicator is mounted on the front surface of the main body. Rapid connection and disassembly can be achieved by installing a connecting hole, when connection is conducted firstly, a connecting block is inserted into the connecting hole, an inclined plate collides with a movable rod, the movable rod returns to the original position under the action of a first spring, the inclined plate is limited, the inclined plate and the connecting block are prevented from sliding off, and the connecting function is achieved; a pressing rod moves to drive a second spring to extend, the pressing rod drives a gear groove to move, a driving gear and a rotating shaft are made to rotate, a cable is tightened to drive a movable rod to contract, and therefore an inclined plate is not limited any more, and the dismounting function is achieved.

Description

technical field [0001] The invention relates to the technical field of flash memory, in particular to a flash memory storage device based on cold and hot data analysis technology. Background technique [0002] Flash memory is a form of electronically erasable programmable read-only memory that allows it to be erased or written multiple times during operation. This technology is mainly used for general data storage, as well as in computers and other digital products. Exchange and transfer data between, such as memory card and U disk. Flash memory is a special type of EPROM that is written in macroblocks. The data on the entire chip will be erased once the early flash memory is erased. Flash memory (FlashMemory) is a long-life non-volatile memory, that is, the data will not be lost when the power is turned off. The stored data information can still be maintained. Flash memory is a variant of electronically erasable read-only memory (EEPROM). Flash memory can be updated fast...
