Abstract: A motion estimation method is provided for generating a motion vector of a to-be-generated frame between two continuous reference frames. The method includes the following steps. A candidate motion vector is obtained according to the position of a to-be-generated block of a to-be-generated frame. Two first reference blocks are obtained from the two reference frames by extending the candidate motion vector from the to-be-generated block to the two reference frames, respectively. Two second reference blocks are obtained from the two reference frames by extending the candidate motion vector from one reference frame to another reference frame. Whether the candidate motion vector is valid is determined according to the positions of the two reference blocks obtained in each obtaining step. The corresponding motion vector of the to-be-generated block is determined according to the valid candidate motion vector.

Abstract: A first read operation is performed using a first voltage level to read data from a memory array. An instant bit count corresponding to a number of bits in the data read from the memory array is determined. A recorded bit count corresponding to a number of bits in the data that was written at a time of writing the data to the memory array is accessed. A difference between the instant bit count and the recorded bit count is obtained. Conditioned on determining that the difference is less than or equal to a first threshold value, the data read from the memory array is output using the first read operation. Conditioned on determining that the difference is greater than the first threshold value, a second read operation is performed using a second voltage level that is distinct from the first voltage level.

Abstract: A synchronous rectifier driver pre-positions a gate of a synchronous rectifier to allow for fast turn-off. The synchronous rectifier driver turns ON the synchronous rectifier by driving the gate at a high level for a period of time that is based on a previous conduction time of the synchronous rectifier. The synchronous rectifier driver thereafter drives the gate at a lower level that is sufficient to keep the synchronous rectifier ON. The synchronous rectifier can be quickly turned OFF by further reducing the level of the drive signal at the gate of the synchronous rectifier.

The word line driver receives a first voltage reference signal, a second voltage reference signal, and an input signal. The word line driver has an output coupled to a word line. The control circuitry is configured to deselect the word line by applying the input signal to the input of the word line driver. For example, in a program operation the word line is deselected to indicate that the word line is not programmed, and another word line is selected to be programmed. During an operation in which the word line is deselected and another word line is selected, the word line discharges through both of a first p-type transistor and a first n-type transistor of the word line driver.
