Abstract: A memory device including a memory cell array, a signal generator, a word line decoder, a bit line decoder, a sensing amplifier circuit and a register circuit is provided. The signal generator generates a control signal according to a wrap around read command. The word line decoder, the bit line decoder, and the sensing amplifier circuit read data stored in the memory cell array according to the wrap around read command, so as to output a first wrap around read data. The register circuit is configured to latch the first wrap around read data and outputs successive wrap around read data according to the control signal and the latched first wrap around read data after the first wrap around read data is output. When the register circuit outputs the successive wrap around read data, the word line decoder, the bit line decoder, and the sensing amplifier circuit are disable.

Abstract: A power-on read circuit includes a power voltage detector, a first voltage booster, a voltage selector, a reference voltage generator and a read voltage generator. The power voltage detector detects a power voltage to generate a control signal. The first voltage booster generates a first boosted voltage according to the control signal. The voltage selector selects the power voltage or the first boosted voltage to generate a selected voltage. The reference voltage generator receives the selected voltage as an operating power source, and generates a reference voltage based on the selected voltage according to the control signal. The read voltage generator generates a second boosted voltage according to the reference voltage and a clock signal, and generate a read voltage based on the second boosted voltage according to the control signal. The read voltage is provided to a memory cell array to perform a data reading operation.
