摘要： A semiconductor memory has a field programmable unit in which logic to inter-convert external signals to be input/output to/from a memory system and internal signals to be input/output to/from a memory cell array is programmed. A program for constructing the logic of the field programmable unit is stored in a nonvolatile program memory unit. Through the field programmable unit, a controller can access the memory cell array, even when the interface of the controller accessing the semiconductor memory is different from an interface for accessing the memory cell array. Therefore, one kind of semiconductor memory can be used as plural kinds of semiconductor memories. This eliminates the need to develop plural kinds of semiconductor memories, reducing a development cost.

摘要： An electronic circuit system has at least three macro circuits and a plurality of signal lines for connecting the macro circuits to one another into a loop. Each of the macro circuits includes a logic circuit and a memory circuit and has a plurality of input terminals and a plurality of output terminals. Signals are transmitted through the loop in a single specified direction in synchronization with a clock signal. Each of the macro circuits receives the signals at the input terminals thereof, accepts the signals if the signals are destined for the macro circuit, and transfers the signals to the output terminals thereof if the signals are not destined for the macro circuit. Even if the macro circuits simultaneously transmit signals, the electronic circuit system transmits the signals in the specified direction through the loop in synchronization with the clock signal up to destination macro circuits.

摘要： A memory controller multiplexes access signals each consisting of a plurality of bits as optical signals and outputs the multiplexed optical signals. At this time, the optical signals whose wavelengths differ depending on memory devices are generated. A memory interface unit demultiplexes the multiplexed optical signals into the original optical signals and converts the demultiplexed optical signals into electrical signals. The memory interface unit determines to which of the memory devices the electrical signals resulting from the conversion should be outputted, according to the wavelengths of the demultiplexed optical signals. This frees the memory controller from a need for transmitting to the memory interface unit a signal for identifying the memory device. The memory interface unit need not include a decoding circuit for identifying the memory device.

摘要： A controlled delay circuit has a first gate chain, and a second gate chain. The first gate chain is used to measure a time difference between a changeover point of a first control signal and a changeover point of a second control signal. The second gate chain, which receives third signals generated in the first gate chain and representing the time difference, is used to provide an appropriate delay time from an input to an output depending on the time difference. The controlled delay circuit is capable of properly controlling the timing of the control signal according to the period of the control signal.
