Title: Associative memory (cam)
Inventor: MIYATAKE HISATADA
IPC: G11C15/00
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To speed up a memory and reduce a consumption power by setting a first and a second switches which are turned on and off between an invertor output and a bit line in accordance with a signal on a word line and, a third and a fourth switches which are turned on and off between the bit line and a bit match node in accordance with an invertor output signal. SOLUTION: A voltage amplitude of a word match line 20 is restricted in a range between a higher potential by a threshold voltage of a PMOS transistor with a back gate bias from a ground potential and a lower potential by a threshold of an NMOS transistor NC: 41 with a back gate bias from a power source potential. The range can be made smaller. Accordingly, the voltage amplitude of the word match line 20 becomes small and a consumption power is reduced. When a precharge potential of the word match line 20 is lowered, boosting a bit line is eliminated although the NMOS transistor is used and a high-speed performance is ensured.

Title: Semiconductor device
Inventor: SHIRAI KOJI
IPC: H01L29/06
Filed: 1986-12-26
Abstract: PURPOSE:To increase breakdown strength without generating the dispersion of breakdown strength characteristics and the deterioration of reliability by forming a third semiconductor region so as to be superposed to one part of a first conductor layer as a field-plate through a first insulating layer. CONSTITUTION:N-type diffusion regions 11, 12 are isolated and shaped into a P-type silicon semiconductor substrate 10. A field-plate 14 constituted of polycrystalline silicon is formed onto the surface near the end section of the diffusion region 11 through an insulating layer 13. The field-plate 14 is shaped so that one part thereof is superposed to the diffusion region 12 isolated from the diffusion region 11. Consequently, the potential of the diffusion region 12 also depends upon a distance between the regions 11, 12, but it is obtained by subtracting only the film thickness section of the insulating layer 13 from the potential of the field plate 14 approximately. As a result, the potential of a field-plate 15 connected to the diffusion region 12 is also lowered. Accordingly, breakdown strength between the diffusion region 12 and the substrate 10 is increased largely, thus elevating breakdown strength without augmenting the film thickness of an interlayer insulating layer.
