<p>PURPOSE:To reduce the power consumption of a ROM and decrease the number of elements, by connecting transfer gates to the drain of a transistor for writing information and the input of an amplifying circuit. CONSTITUTION:Electric power from a power source Vcc is applied through inverters 20 and 20', whose output terminals are connected to data lines 13 and 13'. Then, column selection signal 14 is applied to input teminals of the inverters 20 and 20'. To the data lines 13 and 13', one-side terminals of trasfer gates 21 and 21' are connected, and the other-side terminals are connected to a signal read line 17'. The column selection signal 14 is applied to the gates of the transfer gates 21 and 21'. The signal read line 17' is connected to an amplifying circuit 15.</p> |
