  • Patent number: 7368939
    Abstract: A control circuit receives an external control signal in synchronism with an internal clock and generates an address signal and internal control signals. A data multiplexer has a plurality of input parallel lines and a plurality of output parallel lines and is switched to one of a first output state and a second output state in accordance with the internal control signal. In the first state, the data multiplexer outputs parallel data, which is input to the plurality of input parallel lines and read out from the memory core unit, to the plurality of output parallel lines corresponding to the plurality of input parallel lines. In the second state, the data multiplexer selects 1-bit data of the parallel data input to the plurality of input parallel lines and outputs the 1-bit data to the plurality of output parallel lines. A conversion circuit converts the parallel data into serial data.

  • Patent number: 6577551
    Abstract: A semiconductor integrated circuit includes a control data storage circuit (6) having nonvolatile storage devices with programmed control data and a latch circuit for holding data read out from the storage devices, and a read control circuit (7) for controlling read operations of the control data, which are built in a semiconductor chip. The control data storage circuit (6) is divided into groups (1, 2), and the read control circuit (7) generates read control signals for the groups (1, 2) at different timings, using an output of an internal potential detecting circuit 41 as the timing reference, thereby preventing the peak of power consumption from unacceptably rising during reading operations.
