Chip data copying device and method

Abstract

The invention relates to a chip data copying device and method. A logic control unit is adopted to analyze all partitions of a master slice, master slice analysis result files are obtained, participation of a processor is reduced, the data processing speed can be increased, copying is executed through the logic control unit, the data cache space of the processor is not needed, the hardware cost is saved, the data processing speed is further increased, the processor can be matched with a master slice analysis result file for copying, the copying data size is effectively reduced, the copying time is shortened, the logic control unit can achieve different chip communication protocols, and therefore data copying among various protocol chips is supported, therefore, a corresponding chip data copying device can use the bandwidth of a chip hardware bus to the maximum extent, and the purpose of increasing the data copying speed of a high-capacity chip is achieved.

Description

technical field [0001] The present application relates to the technical field of semiconductor memory chips, in particular to a device and method for copying chip data. Background technique [0002] At present, for large-capacity chip data writing (such as chip storage data capacity greater than 4GBytes), most of them use the method of directly writing data from the computer to the chip, and write data in the case of software participation. operation, cannot make good use of the hardware bus bandwidth, and when multiple chip operations are performed at the same time, the data copy speed is often slow; and some devices use hardware for data writing, but due to the large amount of data, it is difficult to complete The time is also too long; it can be seen that when multiple chips need to write copy data, the traditional chip data copy solution has the problem of slow speed. Contents of the invention [0003] Based on this, it is necessary to provide a chip data copying devi...
