    摘要: An internal address signal is outputted quickly by connecting nMOS transistors in series to inverters forming a latching circuit of a row address buffer circuit, applying an external row address signal to the gate of a nMOS transistor, applying a delayed activation signal .phi.2 to the gate of the nMOS transistors, grounding the gate of the nMOS transistor, triggering nMOS transistors into complete conduction by the delayed activation signal .phi.2 to reduce the ON resistance. A column address buffer circuit receives a ZCAS circuit by an NOR gate, and an external column address signal by an NAND gate during standby, to prevent a flow of a through current.

    摘要: An input transistor unit includes a first transistor having a control electrode to which a reference voltage is supplied. An output transistor unit includes a diode-connected second transistor. At least one of the input transistor unit and the output transistor unit further includes a third transistor that is diode-connected and connected in series with the corresponding first transistor or the second transistor and outputs a current in the same direction as the corresponding transistor does. The number of transistors included in the input transistor unit and the number of transistors included in output transistor unit are different from each other. The size of transistors included in the input transistor unit differs from that of transistors included in the output transistor unit.

    摘要: Until the number of pulse application n reaches 12, as a first-half pulse, a pulse is set to have a width fixed to 2 ms, and its voltage is increased every time. As a latter-half pulse, the pulse is set to have a width fixed to 3 ms and the pulse voltage is increased every time until the maximum voltage is attained. After the maximum voltage is attained, first, the pulse of a width of 3 ms is applied twice, the pulse of a width of 4 ms with the maximum voltage is applied twice, and the pulse of a width of 5 ms with the maximum voltage is applied twice. Even after the maximum voltage is attained, change over time of a threshold voltage can be more linear. Thus, a non-volatile semiconductor memory device allowing efficient programming operation and erasing operation in a short period of time can be provided.

    摘要: A semiconductor memory device is disclosed. A block unit is divided into memory mats based on an internal address. In the case where the internal address is “1”, data are read in ascending order in accordance with a start address from the memory mat, while the internal address is incremented by an address conversion circuit thereby to select a 4-word block including the words next selected from the memory mat. At the same time, the internal address is incremented based on the start address, so that the period for reading each word included in the lowest order of 4-word block can be secured. In the process, the address next to be input can be decoded.

    摘要: If a region designated by an address signal is a logic control region, an interface portion transmits/receives data to/from a register instead of a DRAM. A data signal used at that time is a control command for a logic circuit held in the register or input data for a process in the logic circuit. Depending on the content held in the register, the logic circuit performs, for example, an encryption process or a process which takes for a microcomputer a long time to complete such as an image processing. The result of processing is stored in the register and read in a sequence of reading from the DRAM.
