Embodiment Construction

[0031] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0032]For memory products, products made with a single bit of a memory, generally a bit-line (word-line) usually controls the activity of a bit, as shown in Figure (1). Generally speaking, a digital control signal can only control two situations of 'on' or 'off'. The most basic principle of the present invention is to send out a control signal to flexibly adjust one or more word-lines at any time according to customer requirements. This control signal is implemented as a multiplexer (MUX). This is an extension of the control signal. Here is an example to explain by controlling one word line and controlling two word lines.

[0033] Assuming that the control signal is 0, only one word line can be opened or controlled in each clock segment in the chip, and only one unit bit is working in each memory cell at that time. When the control signal is 1, two word lin...

Abstract

The invention relates to a memory capable of being changed to multiple specification requirement grades and an operating method thereof. The memory comprises a plurality of storage bit units, control units corresponding to storage bits, word line (WL) control units of the storage bits and a selector unit which can change the memory to the corresponding specification requirement grades by changing a metal layer, wherein the selector unit outputs signals of a selector to select different specifications or corresponding grades of memories; the WL control units receive the signals of the selector output by the selector unit of the same specification grade of memory to control the WL required at different specification grades; and the corresponding one WL can be controlled each time, or the corresponding two WLs can be simultaneously controlled or a plurality of corresponding WLs can be simultaneously controlled to achieve selection of different specification grades of memories. The memory has a compact structure, reduces the time from the product to the market, can reduce the use cost of chips and has a wide range of application.

Description

technical field [0001] The invention relates to a memory and a preparation method thereof. Using the principle of backup, memory cells are copied in the same chip, thereby greatly improving the reliability of the chip and reducing the risk of file damage. The invention belongs to the technical field of integrated circuits. Background technique [0002] In the electronics industry, the different requirements for product specifications for military, commercial, and civilian applications vary significantly. Military instruments generally work in extreme environments for a long time, which requires extremely high reliability of products. Civilian products such as mobile phones and computers are updated very quickly, so the requirements for the characteristics of electronic components, such as erasable times, error rate, and service life, are relatively low. [0003] For different specification requirements, memory manufacturers often need to design and plan corresponding produ...
