Problems solved by technology

However, since the size of the current rewritable non-volatile memory storage device is getting smaller and smaller, the heat accumulation problem of the rewritable non-volatile memory storage device is becoming more and more serious.
If heat dissipation is not done well to control the overall temperature of the rewritable non-volatile memory storage device, the rewritable non-volatile memory storage device is prone to data loss due to accumulated heat, and even faster aging

Embodiment Construction

[0065] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In addition, wherever possible, elements / components using the same reference numerals in the drawings and embodiments represent the same or similar parts.

[0066] Generally speaking, a memory storage device (also known as a memory storage system) includes a rewritable non-volatile memory module (rewritable non-volatile memory module) and a memory controller (memory controller, also known as a memory control circuit). Typically, a memory storage device is used with a host system so that the host system can write data to or read data from the memory storage device.

[0067] Figure 1A is a schematic diagram of a host system using a memory storage device according to an exemplary embodiment of the present invention.

[0068] The host system 1000 includes a computer 1100 and an input / output (I / O) device 1106 . The com...

Abstract

A memory storage device, a memory controller and a temperature management method are provided. The temperature management method is suitable for the memory storage device having a rewritable nonvolatile memory module and a memory controller for controlling the rewritable nonvolatile memory module. The temperature management method comprises: detecting and determining whether the hot spot temperature of the memory storage device is higher than a preset temperature; and, if so, enabling the memory controller to perform a cooling process so as to reduce the hot spot temperature of the memory storage device. In this way, accumulated heat of (rewritable nonvolatile) memory storage device can slow down, thereby the problem of data loss and aging of (rewritable nonvolatile) memory storage device slows down.

Description

technical field [0001] The invention relates to a hot spot temperature management method for a memory storage device and a memory controller and a memory storage device for implementing the method. Background technique [0002] The rapid growth of digital cameras, mobile phones and MP3 players in recent years has led to a sharp increase in consumer demand for storage media. Because rewritable non-volatile memory (rewritable non-volatile memory) has many characteristics such as data non-volatility, low power consumption, small size, no mechanical structure and fast read and write speed, it is most suitable for use in portable electronic products , such as mobile phones, personal digital assistants, and notebook computers. [0003] In addition, because the rewritable nonvolatile memory (such as a flash drive using the rewritable nonvolatile memory as a storage medium) has a small size and a large capacity, it has been widely used for storing important personal data. Therefor...
