Problems solved by technology

However, this data backup method is to store the data in the flash memory 18 in clear code, and the data security is insufficient.
Simultaneously, in order to ensure the integrity of data backup, the storage capacity of flash memory 18 must be greater than or equal to the storage capacity of internal memory 10, cause the utilization rate of flash memory 18 to be too low (1: 1), increased data backup cost

Embodiment Construction

[0012] Such as figure 2 Shown is a hardware architecture diagram of the memory used in the data backup method of the present invention. The memory 5 is connected to the north bridge 11 through a connector (such as a PCI-E interface) 12, and the north bridge 11 is connected to the memory 10 through a data line (such as a DDR2 data line). Wherein, the memory 5 includes: a backup power supply 13, a power supply controller 14, a power supply control program 15, a system control chip (such as System-on-Chip, SoC) 16, a field programmable gate array (Field Programmable Gate Array, FPGA) 17. Flash memory (Flash Memory) 18, step-down circuit (such as Point of Load, POL circuit) 19, memory module 20, etc. In this embodiment, the memory module 20 is: DDR2 DIMM (Dual In-line Memory Modules, dual in-line memory module), and the power control program 15 can be solidified in a chip, such as a PROM (Programmable Read- Only Memory, programmable read-only memory).

Abstract

The invention relates to a data backup method of a memory. The method comprises the following steps of: starting a backup power supply when electronic equipment powers off; controlling a chip to read out the data in the internal memory by using the system, and writing into a field programmable gate array; and coding the date by using the field programmable gate array and storing the coded data toa fast flash memory. The invention also provides a memory for data backup. By utilizing the memory, the data in the internal memory can be coded and compressed and then stored to the fast flash memory after the electronic equipment powers off.

Description

technical field [0001] The invention relates to a memory design method, in particular to a memory and its data backup method. Background technique [0002] The data backup technology after a sudden power failure of the computer system has been widely used in the field of memory design. refer to figure 1 As shown, it is a traditional memory design. When the computer system is powered off, the system control chip 16 directly copies the data in the internal memory 10 to the flash memory (Flash memory) 18. The data in the memory 18 is sent back to the memory 10 . However, this data backup method is to store the data in the flash memory 18 in clear code, and the data security is insufficient. Simultaneously, in order to ensure the integrity of data backup, the storage capacity of flash memory 18 must be greater than or equal to the storage capacity of memory 10, resulting in the utilization rate of flash memory 18 being too low (1:1), increasing the cost of data backup. Cont...
