Abstract
A read voltage tracking method, a memory storage device and a memory control circuit unit are provided. The method includes obtaining a plurality of test read voltages corresponding to a plurality of voltage adjustment values, and obtaining an optimal read voltage according to the voltage adjustment values. The step of obtaining the test read voltages includes obtaining a second test read voltage by adjusting a first test read voltage according to a first voltage adjustment value, and obtaining a third test read voltage by adjusting the second test read voltage according to a second voltage adjustment value, and the first test read voltage is a preset test read voltage, the first voltage adjustment value is a preset voltage adjustment value, and the first voltage adjustment value is different from the second voltage adjustment value.
