While a manual control is effective, the change-over switches 91, 92 are changed over to the M sides so that charge held in the holding condenser 7 can be increased and decreased by operation of push buttons 11, 12 of a manual regulator 6. Simultaneously, a difference between the output e 5  and the recording controller output e 3  is obtained at a comparator 10 and is applied to an integrator circuit of the recording controller 1 whereby e 3  and e 5  are equalized to each other so that a changing over to the automatic control from the manual control could not cause a bump to occur.

Abstract: PURPOSE:To obtain a bipolar type erasable P-ROM by breaking down an emitter-base junction in a transistor selected, flowing reverse currents and changing a current amplification factor. CONSTITUTION:An erasable P-ROM is constituted by arranging N-P-N transistors Trs 11-14, 21-24, 31-34 sharing a collector in a matrix shape. When an information is intended to be transmitted over the TR such as the TR11 of X1 and Y1 in the constitution, an emitter junction in the TR11 is broken down at 6-7V when voltage is applied between X1 and Y1 terminals so that X1 is brought to a positive value. When 1mA currents are flowed for approximately 40sec at that time, a current amplification factor hFE reduces to half the initial state, and the information is written. On a reading, positive voltage is applied to Y1, and X1-X3 each grounded by load resistors are scanned. Accordingly, the difference of voltage appears between X1 and X2.
