Problems solved by technology

[0003] In addition, since such a memory storage device with a rewritable non-volatile memory is operating at a high speed, for example, when writing and reading a large amount of data, it needs to consume a lot of energy and generate a lot of heat, so it is easy to Cause the temperature of the memory storage device to be too high, reduce its access efficiency or cause its damage

[0073]Generally speaking, a memory storage device (also called a memory storage system) includes a rewritable non-volatile memory module and a controller (also called a control circuit). Typically memory storage devices are used with a host system so that the host system can write data to or read data from the memory storage device.

[0074] Figure 1A is a schematic diagram of a host system and a memory storage device according to the first embodiment of the present invention, Figure 1B is a schematic diagram of a computer, an input / output device and a memory storage device according to an embodiment of the present invention, Figure 1C It is a schematic diagram of a host system and a memory storage device according to an embodiment of the present invention.

[0075] Please refer to Figure 1A , the host system 1000 generally includes a computer 1100 and an input / output (input / output, I / O for short) device 1106 . The computer 1100 includes a microprocessor 1102 , a random ...

[0120] The memory storage device and the host system of the second embodiment of the present invention are essentially the same as the memory storage device and the host system of the first embodiment, wherein the difference is that the first accumulated value of the second embodiment can be based on the temperature of the memory storage device adjusted for changes. The following will use Figure 1A , figure 2 and image 3 The difference between the second embodiment and the first embodiment will be described using the structure of the device.

[0121] In this embodiment, in the operation of setting the first accumulated value, the memory control circuit unit 104 (or the memory management circuit 202) will detect the temperature of the memory storage device 100, and determine whether the temperature of the memory storage device 100 is greater than or equal to temperature threshold. If the temperature of the memory storage device 100 is not greater than or equal to the temp...

Abstract

The present invention provides a data transmission method, a memory control circuit unit and a memory storage device. The method includes: initially setting a first threshold value and a first accumulation value; value plus the first accumulated value to update the first threshold value. In addition, when the detected temperature of the memory storage device is greater than or equal to the temperature threshold, it is judged whether the size of the received write data is greater than or equal to the first threshold; and if not, the write data is written into the rewritable The non-volatile memory module also updates the first threshold by subtracting the size of the written data from the first threshold. Otherwise, the write data is not written into the rewritable non-volatile memory module. Based on this, the method can effectively avoid the system overheating phenomenon caused by the operation of the memory storage device.

Description

technical field [0001] The present invention relates to a data transmission method, and in particular to a data transmission method, a memory control circuit unit and a memory storage device. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Since rewritable non-volatile memory (rewritable non-volatile memory) has the characteristics of data non-volatility, power saving, small size, no mechanical structure, fast read and write speed, etc., in recent years, rewritable non-volatile memory The memory industry has become a very popular part of the electronics industry. For example, a solid-state drive using flash memory as a storage medium has been widely used as a hard disk of a computer host to improve the access performance of the computer. [0003] In addition, since such a memory storage device with a rewritable non-volatile memory is operating...
