Embodiment Construction

[0038] In an embodiment of the present invention, the P+ / N well junction diode acts as a program selector for the programmable resistive element. The diode can include P+ and N+ active regions in the N-well. Since the P+ and N+ active regions and the N-well are manufactured using off-the-shelf standard CMOS logic processes, these devices can be fabricated in an efficient and cost-effective manner without requiring additional masking or process steps to save costs. The programmable resistive element can be included in the electronic system.

[0039] Figure 4 Shown is a block diagram of a memory cell 30 using junction diodes in accordance with one embodiment. In particular, the memory cell 30 includes a resistor assembly 30a and a diode 30b. Resistive component 30a may be coupled between the anode of junction diode 30b and the positive voltage V+. The cathode of junction diode 30b may be coupled to negative voltage V-. In one embodiment, the memory cell 30 may be a fuse me...

Description

technical field [0001] The invention relates to a programmable memory component, especially a programmable resistance component of a memory array, a one-time programmable memory, a programmable resistive component memory, an electronic system, an electric fuse memory and a method. Background technique [0002] Programmable resistive components generally mean that the resistive state of the component can be changed after programming. The resistance state can be determined by the resistance value. For example, the resistive component can be a One-Time Programmable (OTP) component (such as an e-fuse), and the programming method can apply a high voltage to generate a high current through the OTP component. When a high current flows through the OTP device by turning on the program selector, the OTP device will be programmed by firing into a high or low resistance state (depending on whether it is a fuse or an antifuse). [0003] Electrical fuse is a common OTP, and this program...
