    摘要: This invention relates to a protection device of a semiconductor device. The present invention can prevent the drop of a gate breakdown voltage due to miniaturization of a device without impeding the high speed performance of the circuit attached thereto. The invention improves the voltage that can be applied to the input terminal of the device by reducing the surface breakdown voltage of a surface breakdown type MOS transistor, which is a principal member of a protection device, and reducing the resistance after the breakdown. This can be accomplished, for example, by increasing the concentration of a region in which the MOS transistor is disposed, by reducing the depth of the region, and so forth.

    摘要: A static RAM memory is divided into a plurality of mats (12). Word lines (16) in each pair of mats are accessed by an x-decoder (14). Columns or bit lines are accessed by a y-decoder (20) which selectively connect pairs of bit lines (22) to common data bus segments (24). Transistors (60, 62) connect selected bit lines with a load during a write cycle to stabilize those bit lines and memory cells into which data is written. The x-decoders are connected with near word lines (16a) for addressing a near half of each mat and are operatively connected with remote word lines (16b) for addressing word lines in a remote half of each mat. In this manner, each mat is divided into two effective mats. The bit lines of all the effective mats within an actual mat are connected with the same output data bus segment. A pair of sensing amplifiers (32) is provided for each bit of memory which is accessed concurrently, e.g. eight bits, such that the high and low output of each flip-flop memory cell (18) are both amplified. A pair of driving amplifiers (34) further amplify each high and low output before applying them to an output data bus (38).

    摘要: This invention relates to a tri-state type driver circuit in which any one of the three possible output signals of "float", "on", or "off" is produced at high speed even when an output terminal is accompanied with a great load. The tri-state type driver circuit comprises an output inverter circuit which employs a bipolar transistor as a load thereof and a MOS-FET as a driver thereof, a first logical circuit which is coupled to an input terminal of the bipolar transistor, which first logical circuit is made up of a C-MOS circuit receiving an external select signal and a C-MOS circuit having an input signal transmitted thereto and whose output can be specified by the external select signal, and a second logical circuit which is coupled to an input terminal of the MOS-FET, which second logical circuit is made up of a C-MOS circuit receiving the external select signal and a C-MOS circuit having the input signal transmitted thereto. The state of the external select signal will determine whether the driver circuit output will be "float" (regardless of the input to the driver circuit) or "on" or "off" (in correspondence with the input to the driver circuit).

    摘要: In a defect relieving technology which replaces defective memory cells of a semiconductor memory device by spare memory cells, use is made of an associative memory. Address information of a defective memory cell is stored as a reference data of the associative memory, and new address information of a spare memory cell is written down as output data of the associative memory. A variety of improvements are made to the associative memory. For instance, a plurality of coincidence detection signal lines of the associative memory are divided into at least two groups, and one group among them is selected by switching means. Reference data of the associative memory comprises three values consisting of binary information of "0" and "1", and don't care value "X". The associative memory further includes a plurality of electrically programable non-volatile semiconductor memory elements.
