Embodiment Construction

[0105] 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 such that the host system can write data to or read data from the memory storage device.

[0106] Figure 1A It is a schematic diagram of the connection between the host system and the memory storage device shown in an embodiment of the present invention. Figure 1B It 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 shown in an embodiment of the present invention.

[0107] Please refer to Figure 1A , the host system 1000 generally includes a computer 1100 and an input / output (input / output, I / O) device 1106 . The computer 1100 includes a microprocessor 1102 ...

Abstract

The present invention provides a random number generation method, a memory storage device and a control circuit. The random number generation method of the present invention can be used for the rewritable type nonvolatile memory module, wherein the rewritable type nonvolatile memory module comprises a plurality of storage units. The random number generation method comprises: writing a data into the plurality of the storage units; repeatedly reading at least one of the storage units by using a first reading voltage so as to obtain a plurality of sensing currents; and generating at least a random number according to the sensing currents. The present invention provides the random number generation method, the memory storage device and the control circuit, wherein the generated random number does not have regularity.

Description

technical field [0001] The invention relates to a method for generating random numbers for a rewritable non-volatile memory module, a memory storage device and a control circuit. 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 the rewritable non-volatile memory module (for example, flash memory) has the characteristics of data non-volatility, power saving, small size, and no mechanical structure, it is very suitable for being built into various portable multimedia devices listed above. . [0003] In some encryption / decryption techniques, the use of random numbers is very common and important. Standard random numbers must meet the principles of being unpredictable, changing over time, and non-repetitive. Generally speaking, random numbers are mainly generated by a random number generator (random number generator). However, with the cont...
