Decoding method of power supply line of memory array

Abstract

The invention provides a decoding method of a power supply line of a memory array, which is a method for selectively supplying voltage supply in an integrated circuit memory device. In the method, an integrated circuit device is provided and comprises multiple first memory units; each memory unit comprises a power supply terminal and a grounding terminal; multiple second memory unit are selected from the multiple first memory units; a first power supply voltage is supplied to the power supply terminal of each memory unit selected, and a second power supply voltage is supplied to the power supply terminal of each unselected memory unit; and the second power supply voltage is lower than the first power supply voltage. In an embodiment of the method, a first grounding voltage is applied to the grounding terminal of each selected memory unit, a second grounding voltage is applied to the grounding terminal of each unselected memory unit, and the second grounding voltage is higher than the first grounding voltage.

Description

technical field [0001] The present invention relates to a memory device and a method for providing a voltage supply thereof Background technique [0002] Integrated circuits, or "ICs," have grown from a handful of interconnected devices fabricated on a single chip of silicon to millions of devices. Existing ICs offer performance and complexity far beyond what was originally imagined. To achieve increases in complexity and circuit density (ie, the number of devices that can be packed onto a given chip area), the size of the smallest device feature, also referred to as device "geometry," has shrunk with each IC generation. Semiconductor devices are now being fabricated with feature sizes smaller than 1 / 4 micron.

Problems solved by technology

Although fabless chip companies and foundry services have increased in recent years, many limitations remain

For example, leakage currents in memory devices make it difficult to reduce overall device power consumption due to scaling of logic devices and designs operating at low voltages

Memory devices such as static random access memory (SRAM) consume large amounts of power in many integrated circuit applications
