This application provides a method and device for detecting the installation of a memory chip. When the memory chip is powered on, the current monitoring chip obtains the output current of the power supply terminal of the memory chip, converts the output current into a first level signal, and converts the first level signal to a hysteretic comparator. The hysteresis comparator compares the voltage value of the first level signal with a preset first threshold and a preset second threshold respectively, and sends the compared second level signal to the processing chip. Wherein, the preset first threshold is smaller than the preset second threshold, and the second level signal includes a high level signal or a low level signal. The processing chip determines the installation condition of the memory chip according to the second level signal. In this application, when the memory chip is powered on, the current monitoring chip and the hysteresis comparator are used to judge whether the output current of the memory chip is abnormal. The chip was accidentally damaged due to incorrect installation.
Description
technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a method and device for detecting the installation of a memory chip. Background technique [0002] During the production and development process of the server, it is necessary to test and debug the flash memory chip in the server. When testing and debugging the memory chip, it is necessary to install the memory chip on the base of the memory chip. Since the pins of the memory chip are symmetrically distributed in double columns, the debugger may install the memory chip upside down on the base of the memory chip, causing the memory Chip installation error. If the memory chip is installed incorrectly, it will cause the memory chip to work abnormally and affect the use of the server. If the installation error of the memory chip is not discovered in time, the memory chip will heat up and burn out due to abnormal operation. [0003] Therefore, there is an urge...
