Method for testing power consumption of memory

Abstract

The invention discloses a method for testing the power consumption of a memory. The method comprises the following steps of connecting a resistor to the memory in series by using a memory increasing card; measuring current passing through a memory bank by the resistor; then multiplying the current by VDD (Voltage Drain Drain) of the memory to accurately calculate the power consumption of the memory; meanwhile, calculating values of the power consumption in different states by combining a memory pressure procedure under the system. Compared with the traditional method for testing the power consumption of the memory, the method for testing the power consumption of the memory, has the advantages that the accuracy is higher; the power consumption values of the memory in different states can be tested; the power consumption conditions of the memories from all manufacturers can be transversely compared, so the convenience is brought to the selection of customers; the simplicity and feasibility for operation are realized; higher practicality and better popularization and use prospect are obtained.

Description

technical field [0001] The invention relates to memory testing technology, in particular to a method for testing memory power consumption. Background technique [0002] At present, the main method of testing memory power consumption is to calculate the power consumption of the memory by multiplying the current of the server motherboard and the voltage of the memory VDD (power terminal), there will be some errors in power consumption, because part of the test is to give The processor on the motherboard of the server is powered by other devices, so that the power consumption of the processor is also included in the test power consumption value of the memory, which will cause inaccurate calculation of the memory power consumption, resulting in a large error in the memory power consumption data. SUMMARY OF THE INVENTION [0003] Aiming at the shortcomings of the prior art, the present invention provides a relatively simple, easy-to-operate, and high-sensitivity memory power co...

Problems solved by technology

[0002] At present, the method of testing memory power consumption is mainly to calculate the power consumption of the memory by multiplying the current of the server motherboard and the voltage of the memory VDD (power supply terminal). There will be some errors in power consumption, because part of the test is for The processor on the main board of the server is powered by other devices such as the processor, so the power consumption of the processor is also included in the test power consumption value of the memory, which will cause inaccurate calculation of memory power consumption and cause large errors in memory power consumption data.
