摘要:
A specifying circuit specifies either the first masking method or the second masking method. A first generation circuit generates a signal corresponding to the first method. A second generation circuit generates a signal corresponding to the second method. A third generation circuit generates a write pulse signal on the basis of the output signal of the first generation circuit in response to the specification of the first masking method made by the specifying circuit and on the basis of the output signal of the second generation circuit in response to the specification of the second masking method made by the specifying circuit.
摘要:
A row access command and column access command are supplied as one packet to an FCRAM in two successive clock cycles in order to shorten random access time and random cycle time. At this time, definition of the read/write operation is made by use of a first command and a decode address of a memory cell array is fetched in response to the first command. When the decode address of the memory cell array is fetched in response to the first command, command control pins of the conventional SDR/DDR-SDRAM are used as address pins.
