Memory chip, memory device and memory system comprising same device

Abstract

The present application relates to a memory chip in which a power voltage is independently supplied to a memory cell array and a peripheral circuit, a memory device and a memory system comprising thesame device. A memory device according to an embodiment of the present invention comprises: at least one memory chip comprising a memory cell array consisting of an array of memory cells and a peripheral circuit which is positioned around the memory cell array and in which a power line electrically independent from the memory cell array is formed; and a power voltage supply for supplying a power voltage to the memory cell array and the peripheral circuit, wherein the power voltage supply independently supplies the power voltage to each of the memory cell array and the peripheral circuit.

Description

technical field [0001] The present application relates to a memory chip, a memory device, and a memory system including the memory device that independently supply power supply voltages to a memory cell array and peripheral circuits. Background technique [0002] With the development of storage technology, storage devices are becoming more and more integrated, and performance needs to be improved. To this end, it is necessary to develop storage devices that can reduce the size of the storage chip by improving the design of the storage chip and can work faster with the same power. chip. [0003] Conventionally, one power supply voltage is supplied from the outside of the memory chip, and a power supply voltage for the memory cell array (VDDA) and a power supply voltage for peripheral circuits (VDDP) are generated and used within the memory chip by a separate internal power supply voltage generating circuit. figure 1 is a diagram showing the structure of a conventional storag...
