    摘要： There is provided a method of controlling an internal address signal of an RAM in which a late-write method is realized on a chip. Two sets of address registers for reading and writing are provided for each address and further a middle register is provided between the two sets of address registers. The middle register is controlled by a signal formed by obtaining the AND result of a clock signal and a write enable signal and the two sets of address registers for reading and writing are controlled only by the clock signal. A selection circuit selects outputs of the two sets of address registers as an input in accordance with the write enable signal to control an internal address.

    摘要： A static RAM includes pre-amplifiers, which are made up solely of emitter-follower transistors having their collectors supplied with the power voltage, in one-to-one correspondence to sub common data line pairs which are connected by column switches to complementary data line pairs of memory arrays. The pre-amplifier is provided with a first switch which turns on during the selected state to connect the sub common data line pair to the bases of the transistors and a second switch which turns on during the unselected state to provide the bases with a certain bias voltage lower than the readout signal voltage on the sub common data line pair. The emitter-follower transistors have their emitters connected commonly to form common emitter lines, which are connected to pairs of input terminals of main amplifiers made up of CMOS transistors.

    摘要： An information processor having a high performance as a whole is provided by improving the throughput of the processor and the semiconductor memory device. The information processor comprises a memory having a buffer for temporarily holding data and a processor having a memory interface part for controlling the memory to transfer data to the buffer before determining whether the data is to be written in the memory and to write the data in said memory after determining of writing. Data writing and reading to the semiconductor device is pipelined by justifying data exchange between reading and writing. Since the data transfer timings of reading from a memory and writing in the memory can be executed at the same time, the reading process and the writing process can be performed by pipeline-like process and the throughput can be improved.
