An SD memory maintenance practices, use multimeter measuring method of memory chips
On the motherboard and memory data pins is 64, D0-D63, in order to protect the memory data bit feet, in the D0-D63 which 64 data bits plus feet with a small resistance resistor (10 EU) threshold flow effect. On the motherboard and memory data pins is 64, D0-D63, in order to protect the memory data bit feet, in the D0-D63 which 64 data bits plus feet with a small resistance resistor (10 EU) threshold flow effect. While the test Instrument The main principle is to repeat tests with the program memory chips of each data bit pin to see if there is no breakdown or short circuit pin data bits, there is a chip's clock pin, the address pins.
The tester main principle is to use program to repeat tests of memory chips for each data bit pin to see if there is no breakdown or short circuit pin data bits, there is a chip's clock pin, the address pins. Therefore, when the test chip with a multimeter Test methods can also be used to measure, so long as Hong Bi-to-ground (one foot), black pen Pai Yin resistance of the resistance measurement is the resistance of the memory chip data bits to determine which chips are bad, normal, then each data bit the same resistance. Therefore, the use multimeter test chip tester can also be used when the method to measure, so long as Hong Bi-to-ground (one foot), black pen Pai Yin resistance of the resistance measurement is the resistance of the memory chip data bits to determine which chip is bad, the normal resistance, then the same for each data bit. but still there is no tester so intuitive, this method measures the DDR memory chips good or bad. But still there is no tester so intuitive, measurable in this way is good or bad DDR memory chips.

According to the use of manual measurement of memory in the 2A, 2B here, refers to a single group and the dual meaning. According to the use of manual measurement of memory in the 2A, 2B here, refers to a single group and the dual meaning. But the 16-bit chip has eight, but also the equivalent of two 8-bit chips, 16 is quite in the two groups. But the 16-bit chip has eight, but also the equivalent of two 8-bit chips are also the equivalent of two groups of 16. 2A for the second group, 2B for the first group. 2A for the second group, 2B for the first group. Measurements in each group will be cyclic tests for each data bit of a chip feet. Cycle test will be measured in each group for each data bit of a chip feet. Usually measured 3 times -5 times not bad is good. Generally measured 3 times -5 times not bad is good. A good chip: PASS. Good chip: PASS. A bad chip on the show the bad data bit pins. A bad chip on the show the bad data bit pins.
