Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device that requires small footprint and allows in increase in integration degree and memory capacity.  <P>SOLUTION: The number of wires per unit memory cell is reduced by sharing a bit line with a write transistor and a read transistor. Data are written by turning on the writing transistor. The potential of the bit line is supplied to a node where one of a source electrode or drain electrode of the write transistor and the gate electrode of the read transistor are electrically connected. By turning off a writing transistor thereafter, a predetermined amount of electric charge is held in the node. In reading information, a signal line connected to a capacitor as a reading signal line or a signal line connected to one of the source electrode and drain electrode of the read transistor is used as a reading signal line, to supply a read potential to the read signal line, and then, to detect the potential of the bit line.  <P>COPYRIGHT: (C)2011,JPO&INPIT

IPC: A63F7/02
Filed: 2011-02-03
Abstract: <P>PROBLEM TO BE SOLVED: To make it hard to fraudulently generate a jackpot even if such fraudulence as fraudulent feeding of interrupt signals or resetting signals is performed.  <P>SOLUTION: In an initialization process, a CPU outputs a latch signal. The latch signal is fed from an output port to a latch circuit. The latch circuit inputs a counted value of a counter when the latch signal is input, and latches the value. The CPU inputs the data as the initial value of random number for determination latched in the latch circuit via an input port, and sets the input value in a random 1 generating counter for generating a random number for jackpot determination. The data latched in the latch circuit are the values counted by the counter counting clock signals from a second oscillation circuit for outputting clock signals which do not synchronize with clock signals from a first oscillation circuit for determining the motion frequency for the CPU, and so are irregular values. As a result, the initial value of the random 1 generating counter is also irregular.  <P>COPYRIGHT: (C)2011,JPO&INPIT
