摘要: A memory array is divided into memory blocks each including a predetermined number of rows, and voltages on storage nodes are boosted by changing cell plate voltages in the memory block including a selected word line. An unselected word line is held at a negative voltage level when the selected word line is driven to a power supply voltage level. Thereby, it is possible to prevent movement of charges due to connection of a bit line with the storage node at the time of change in cell plate voltage of an unselected memory cell, and destruction of data in the unselected memory cell can be prevented. A dynamic semiconductor memory device not requiring a boosted voltage is provided.

摘要: A semiconductor device includes a PMOS transistor and an NMOS transistor. In a standby state, a potential of Vcc level is applied to the substrate of the PMOS transistor and a potential of Vss level is applied to the substrate of the NMOS transistor. Therefore, the voltage between the source and substrate of the P and NMOS transistors becomes 0 V. In an active state, potentials that render the voltage between the source and substrate lower than the built-in potential are applied to respective substrates of the P and NMOS transistors. Therefore, the threshold voltage of the transistor is lowered in an active state than in a standby state, and almost no leakage current flows between the source and substrate.

摘要: By using a fact that a bit error in an on-chip embedded memory occurs at a random address, means for creating a chip-unique ID and utilizing this ID are provided. A controller having received a verification request from outside instructs a variable power supply circuit to decrease a voltage supplied to a memory to be lower than that at the normal operation time. When the voltage supplied to the memory is stabilized, the controller requests a memory test to a memory BIST. By using an address where an error occurs due to a result of the memory test, the controller creates the chip-unique ID and uses the ID as a response to the verification request.

摘要: An ePLX unit includes a logic unit having an SRAM and a MUX, and a switch unit having an SRAM and a TG for establishing wiring connection in the logic unit. When a composite module is set in the first mode, an Add/Flag control unit uses the SRAMs as a data field and a flag field, respectively, to autonomously control the read address of each of the data field and the flag field in accordance with a control flag stored in the flag field. Furthermore, when the composite module is set in the second mode, the Add/Flag control unit writes configuration information into each of the SRAMs to reconfigure a logic circuit. Consequently, the granularity of the circuit configuration can be rendered variable, which allows improvement in flexibility when configuring a function.

A storage transistor has impurity diffusion regions, a channel formation region, a charge accumulation node, a gate oxide film, and a gate electrode. The gate electrode is connected to a gate line and the impurity diffusion region is connected to a source line. The storage transistor creates a state where holes are accumulated in the charge accumulation node and a state where the holes are not accumulated in the charge accumulation node to thereby store data “1” and data “0”, respectively.

摘要: A CAM (Content Addressable Memory) cell includes first and second data storage portions storing data, horizontal port write gates for storing data applied through a match line pair in the data storage portions in a data write through a horizontal port, and search/read gates for driving the match lines of the match line pair in accordance with the data stored in the data storage portions in a search operation and in a data read through the horizontal port. The match lines are used as horizontal bit line pair, or signal lines for accessing the horizontal port. As the first and second data storage portions are used, it becomes possible to store ternary data, and accordingly, a write mask function of inhibiting a data write at a destination of data transfer is realized. Further, as the CAM cell is used, an arithmetic/logic operation following a search process can be executed selectively, and high speed data writing/reading becomes possible.
