VOLTAGE PREDICTION METHOD, MEMORY STORAGE DEVICE AND MEMORY CONTROL CIRCUIT UNIT

A voltage prediction method, a memory storage device and a memory control circuit unit are disclosed. The method includes: reading a plurality of memory cells in a rewritable non-volatile memory module by using a first read voltage level to obtain count information, and the first read voltage level is configured to distinguish a first state and a second state adjacent to each other in a threshold voltage distribution of the memory cells, and the count information reflects a total number of first memory cells meeting a target condition among the memory cells; and predicting a second read voltage level according to the count information, and the second read voltage level is configured to distinguish a third state and a fourth state adjacent to each other in the threshold voltage distribution.
