Device and method for reading and writing memory chip

Abstract

The invention discloses a memory chip reading and wiring device which is connected to a memory chip test control end and a measured memory chip; the device comprises: an application control procedure which is arranged at the memory chip test control end, the application control procedure is provided with a reading and wiring module which can read and write data in the measured memory chip; a reading monitoring module which can monitor whether the procedure in the measured chip is read or not; a reading and wiring interface which is electrically connected between the memory chip test control end and the measured memory chip, a microprocessor is arranged in the reading and writing interface, the microprocessor is provided with a detection and conversion module which can detect the communication to a port and simultaneously realize the conversion of signals between the interfaces; a signal receiving and sending module which is arranged at the microprocessor and by which the reading and writing interface can be mutually communicated with the signal of the application control procedure; the application control procedure can control the reading and writing interface to read and write the data of the measured memory chip, utilize the read information for carrying out the error analysis and improve the test maintenance efficiency.

Description

technical field [0001] The invention relates to a memory chip read-write device, in particular to a memory chip read-write device which improves and analyzes efficiency. Background technique [0002] Most of the mainboard BIOS storage chips now use SPI (Serial Peripheral Interface) protocol chips as data storage. In the test of the motherboard BIOS, it is necessary to read the data stored in the chip and analyze the data to obtain the results; usually ATE equipment is used to read and write the BIOS storage chip program, but it cannot debug the problematic motherboard, and The data in the chip cannot be read out for analysis, which directly affects the maintenance efficiency of the motherboard. Therefore, be badly in need of a kind of device and can rewrite the data in the SPI BIOS chip when mainboard is repaired or when debugging the mainboard, perhaps the data in the chip is read out and analyzed. At the same time, it can also detect whether the CPU reads and writes the ...
