Abstract: A serial flash memory and an address transmission method thereof. The serial flash memory selectively addresses a first memory space according to a first address length or addresses a second memory space according to a second address length longer than the first address length. If the first memory space is addressed according to the first address length, a first memory address is completely received within an address time duration so that data corresponding to the first memory address is initially outputted from a starting clock. In the address transmission method, if the second memory space is addressed according to the second address length, a portion of a second memory address is received within the address time duration. The other portion of the second memory address is received within a waiting time duration so that data corresponding to the second memory address is initially outputted from the starting clock.

Abstract: A multimode charge pump circuit has a single charge pump that is responsive to a set of clock signals. The set of clock signals is provided in a first mode with a variable frequency according to a first function of the supply potential and temperature, and in a second mode with a variable frequency according to a second function of the supply potential and temperature. Circuitry configures all of the plurality of stages in series during the first mode in order to produce a higher voltage output, and configures a subset of the plurality of stages in series, while disabling the other stages, during the second mode in order to produce a lower voltage output. A precharge circuit is provided that operates as a supply node in the second mode, and as a precharge/clamp in the first mode.

Abstract: A memory is provided. The memory includes a memory cell, a clamp transistor, an inverter, a bit line, a pre-charge path and a detector and controller circuit. The memory is coupled to the clamp transistor. The clamp transistor has a first end, a second end and a control end. The inverter has an input end electrically connected to the second end of the clamp transistor and an output end electrically connected to the control end of the clamp transistor. The bit line is electrically connected to the second end of the clamp transistor and the input end of the inverter and has a bit-line voltage thereon. The pre-charge path is electrically connected to the first end of the clamp transistor through a node having a sensing voltage thereon.

Abstract: A regulator for regulating a program voltage of a memory device is introduced. The regulator includes an operating amplifier, a program path emulation apparatus, and a current mirror coupled to the program path emulation apparatus and the operating amplifier. The current mirror is for controlling a current flowing in the program path emulation apparatus a multiple of a predetermined current. The program path emulation apparatus includes a bit line selection emulation unit for emulating a bit line selecting unit of the memory device, a path resistor for emulating a program path of a memory cell of the memory device, and a sector selection emulation unit for emulating a sector selecting unit of the memory device. The value of the predetermined current may be varied according to the program times of the memory cells of the memory device.
