Circuit and method for controlling cutting positions and controller

Abstract

The invention provides a circuit and a method for controlling cutting positions and a controller. The circuit comprises a logic signal output unit and a logic signal control unit, wherein the logic signal output unit is connected with a DRAM (dynamic random access memory); the logic signal control unit is connected with the logic signal output unit, and is used for receiving multiple inputted logic signals and a cutting position control signal matched with a DRAM model, selecting a logic signal matched with the cutting position control signal from the inputted logic signals according to the cutting position control signal, and sending the matched logic signal to the logic signal output unit; the logic signal output unit is used for outputting the matched logic signal to the DRAM. The circuit has the advantages that the application of different models of DRAM is realized; the function of resistance gating signals is replaced by the selecting function of the logic signal control unit, so that complicated wiring is not needed, the defect of difficulty in wiring of the traditional cutting position control circuit can be effectively overcome; the area of an integrated circuit board is saved, and the design cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic chips, in particular to a cutting position control circuit, method and controller. Background technique [0002] With the increasingly fierce competition in the computer tablet and TV box market, the cost control of the design scheme has become more severe. Memory is one of the most important components of the entire embedded system. In the PCBA (Printed Circuit Board Assembly, printed circuit board) of the solution provider, DRAM (Dynamic Random Access Memory, dynamic random access memory) is one of the most important and expensive components in the entire PCBA. one. [0003] However, due to the limitations of the production process and the complexity and diversity of semiconductor storage, some DRAMs produced on the production line will inevitably have some problematic products. Some DRAMs will have abnormalities in a certain part of the address area, but the rest of the storage area can be ...
