Storage device

Abstract

A description is given of a memory device having memory cells for storing data. The memory device described is distinguished by the fact that a current switch-off device is provided, which prevents an existing current flow through the memory cell to be read in response to the identification of the memory cell content, and / or that a discharge device is provided, which partly discharges again a node in the memory cell which is to be precharged before the memory cell is read.

Description

technical field [0001] The present invention relates to a memory device having memory cells for storing data and a read amplifier with the aid of the magnitude and / or direction of the current regulated by the memory cell when the memory cell is read The contents of the memory cell can be found. Background technique [0002] Many embodiments of this type of storage device have been known for many years. [0003] As in other relatively expensive circuits, when developing storage devices, efforts are also made to keep the energy consumption as low as possible or to reduce it further. Especially in recent years this aspect has achieved greater success. [0004] But for some applications, the energy consumption of storage devices has been very high. [0005] One such application is storage devices for contactless chip cards. [0006] As is known, contactless chip cards are exclusively wirelessly connected to other devices. The energy required for its operation is even transm...
