Detection and identification circuit

Abstract

A test circuit includes a power circuit module arranged on a motherboard of a computer and electrically coupled to first and second idle pins of a memory slot, and an indication module including a number of branch circuits. The indication module is arranged on a memory module. When the memory module is arranged in the memory slot properly, third idle pins of an edge connector of the memory module are electrically coupled to the first idle pins of the memory slot, respectively; and fourth idle pins of the edge connector of the memory module are electrically coupled to the second idle pins of the memory slot, respectively.

Description

technical field [0001] The invention relates to a detection and identification circuit, in particular to a circuit for detecting whether a memory is installed in place. Background technique [0002] As the price of memory sticks drops, more and more users hope to speed up the system by expanding the memory. When installing the memory stick, the user needs to pull out the power plug of the chassis, then open the chassis, and plug the memory stick into the memory slot on the motherboard. Then, power on and detect the motherboard to determine whether the memory module is plugged in place. However, during the process of inserting the memory stick into the memory slot, if the memory stick is not fully in contact with the memory slot, the motherboard will emit an abnormal alarm sound after the power is turned on. At this time, the user needs to disconnect the power again, and re-insert the memory stick into the memory slot of the main board, which will result in a waste of time ...
