摘要： A wake-up circuit of a memory device employs a cascade chain structure in which bit lines are divided into a plurality of blocks, and if the bit lines of one of the blocks are determined to have undergone a wake-up operation based on a bit line voltage fed back in the block, the wake-up operation is performed on a subsequent block. Accordingly, a wake-up delay can be varied, and therefore peak currents can be controlled, thereby reducing overall system power noise.

摘要： Integrated circuit memory devices with latch-free page buffers therein include a page buffer for electrically coupling a bit line from an array of memory cells to a buffer output. The page buffers generate a first logic state at an output thereof when the bit line is at a first logic potential and a high-impedance logic state when the bit line is at a second logic potential, during a memory read operation. An output buffer is also provided for converting the high-impedance state and the first logic state generated by the page buffer to respective opposite logic states (e.g, logic 1 and logic 0). The bit line data is used to directly trigger the appropriate state of the page buffer output by coupling a gate of an insulated-gate isolation transistor to the bit line data and then reading the source of the isolation transistor as the page buffer output.

A first inverter generates a fifth data output signal pair by inverting the third data output signal pair responsive to a first data output control signal. A second inverter generates the fifth data output signal pair by inverting the fourth data output signal pair responsive to a second data output control signal. A first latch generates a sixth data output signal pair by latching the fifth data output signal pair.
