Abstract

The invention relates to the technology of storers and solves problems that a large-area monocrystalline silicon substrate is consumed in a storer containing a passive storage unit circuit and the read-only storer of a combined substrate is hard to make. According to the technical scheme, the storer comprises an insulating substrate, a passive storage unit matrix circuit, a lead line and at least one control chip, the passive storage unit matrix circuit and the lead line are arranged on the upper surface of the insulating substrate, the control chips are in circuit connection with the passive storage unit matrix circuit through the lead line, and the control chips are reversely installed on the upper surface of the insulating substrate. The storer has the advantages of being easy to make and suitable to the real-only storer.

Description

technical field [0001] The present invention relates to memory technology. Background technique [0002] Common memories, such as random access memory, read-only memory and flash memory including active memory unit circuits, resistive memory including passive memory unit circuits, phase-change memory and other memories, are manufactured on a monocrystalline silicon substrate. Memory unit circuits, drive circuits, peripheral circuits, etc. are located on a single crystal silicon substrate. For example, a mask read-only memory disclosed in Chinese patent application number "92109280.6", and a multilayer cross-point resistance memory disclosed in Chinese patent application number "201010175802.8" and its manufacturing method are all circuits integrated in a single crystal On the substrate, although this is easier to manufacture, it will consume a larger area of ​​single crystal silicon substrate, and the cost is higher. [0003] And as Chinese patent application number is " 9...
