Allocation system for access control mode of dynamic random access memory module slot

Abstract

The invention discloses a kind of allotment system of access control mode of dynamic random memory model slot, it includes: a basic input and output system, which records a access mode control program and outputs a control signal when the access mode control program is activated; a chipset, which has two universal input and output interface pins and two access control model output ports, the chipset connects with the basic input and output system, which is used to receive the control signal in order to make the pins to output the first control output and the second control output respectively, the access control model output ports output the first and the secod access control signal; a dynamic random memory model slot, which has three access control mode input ports, and a pair of switches, which is used to receive the first control output and the second control output, and outputs the first and the second access control signal to two ports of the three access control model input ports.

Description

Technical field [0001] The invention relates to an output control system, in particular to an allocation system of an access control mode of a dynamic random access memory module slot. Background technique [0002] With the rapid development of computer technology, the requirements for power saving and data error prevention are increasing. Faced with this requirement, motherboard R&D engineers have studied and designed many related technologies, such as Error Correction Code (ECC) and Suspend to Disk (STD). [0003] ECC technology is mainly used in the memory module of the computer. When the motherboard supports ECC, data errors can be corrected during the process of accessing data from the memory module, making data access more accurate. The STD technology stores the data required for reactivation in the hard disk after the system is shut down or enters the power-saving mode. Once the system is awakened, the system operation status can be restored immediately. However, due to th...
