    摘要: A semiconductor memory device including a serial I/O buffer (19); DRAM cells (1); and SAM cells (4,5) arranged in line, the SAM cells corresponding to the DRAM cells in one row. In the device in a first mode, the SAM cells (4,5) are divided into N first portions each having boundaries, data stored in the SAM cells being transferred to the serial I/O buffer (19) sequentially until the SAM cells in the boundaries of the first portions are transferred to the serial I/O buffer. In a second mode, the SAM cells (4,5) are divided into M (N>M) second portions each having boundaries, data stored in the SAM cells being transferred to the serial I/O buffer (19) sequentially until the SAM cells in the boundaries of the second portions are transferred to the serial input output buffer. The semiconductor memory device further includes a circuit for detecting changes from the first mode to the second mode and from the second mode to the first mode. The semiconductor memory device further includes a circuit for generating a first and a second signals. When a mode is changed from the first mode to the second mode, the circuit generates the first signal. When the mode is changed from the second mode to the first mode the circuit generates the second signal.

    摘要: A Video-RAM semiconductor memory device comprised of a RAM array having an address input for inputting row, column, and target addresses, and a serial access array having a serial output port. The Video-RAM has address/control logic which detects a stimulus such as a RAS clock from an external controller indicating a coarse timing location for a data transfer between the RAM array and the serial access array. The control logic then provides control signals, that are internally synchronized with a serial clock, and that occur during a period that a tap pointer is equal to a value one less than a programmable target value or an input target address. This causes a row in the RAM array corresponding to an input row address to be transferred between the RAM array and the serial access array.

    摘要: A semiconductor memory device has a memory cell array (1) including many memory cells, a first data I/O section (6) for implementing random input and output of data for the memory cells based on an externally-supplied random I/O signal, a second data I/O section (7) for implementing serial input and output of data for the memory cells, a counter (8) for counting the number of externally-supplied basic clock signal cycles, a controller (9) for controlling the I/O of data for the memory cells in accordance with the number of the cycles of basic clock signals. The counter is capable of inputting at least one kind of externally-supplied designation signal, generating a designation control signal for designating a specified cycle which is a count starting cycle for the basic clock signal at each designation signal, issuing instructions for commencement of count for the number of cycles of the basic clock signal in the counter based on the designated control signal, and synchronously controlling designation of addresses based on the number of cycles counted by the counter and the I/O operations of the first data I/O means and the second data I/O means from the specified cycle of the designated basic clock signal.
