摘要： A memory cell includes a load transistor pair serving as a high data holding element, a drive transistor pair serving as a low data holding element, and an access transistor pair for accessing the high data holding element or the low data holding element. A high data holding potential corresponding to the source potential of the load transistor pair is set at a value larger than a supply potential, and a low data holding potential corresponding to the source potential of the drive transistor pair is set at a value larger than a ground potential. In a read operation, a source potential control line of a selected memory cell is connected with a ground line through a source line switch.

摘要： In a signal transmission circuit having a plurality of signal lines for supplying potentials to load capacitances, in which each load capacitance is driven by each signal line, each signal line can be connected to another signal line via a switch. By connecting two signal lines at different potentials to each other by means of said switch, the potentials of the signal lines are changed through the process of charge redistribution, thereby eliminating charging and discharging through a power-source line and a ground line. Therefore, if n load capacitances are equal to each other, the switches are controlled so that the potential variation of each of the signal lines is phase shifted from those of its adjacent signal lines by 1/n. Thus, the load capacitances can be driven with 1/n of the total amount of charge consumed in the case of driving the n load capacitances independently, thereby reducing the consumed current.

摘要： A phase comparison process in a timing recovery process for high-speed data communication defines a data window and compares the phase of a clock in the window with the phase of an edge of data so as to realize a parallel process, wherein the phase comparison and the process of determining whether a data edge lies within the window are performed in parallel to each other, and the phase comparison result is output only if the data edge lies within the window. With this configuration, it is possible to perform an accurate phase comparison process with no errors without requiring high-precision delay circuits.
