Patent GB-1308806-A (GB)
Title: Semiconductor memory using variable threshold transistors
IPC: G11C16/04
Filed: 1970-03-05
Abstract: 1308806 Matrix memory array RCA CORPORATION 5 March 1970 [12 March 1969] 10665/70 Heading G4C [Also in Division H3] The invention relates to a memory array having a. plurality of single field effect bi-stable semi-conductor devices each being able to assume first and second threshold levels. A matrix array is shown in Fig. 3a wherein control electrodes of the transistors are coupled together in rows and are connectable to three voltage sources 1, 2, 3. The transistors are connected between row and column conductors, the column conductors being connectable to voltage sources 1, 2, 3, the row conductors being connectable to voltage sources 1 and 2. Each transistor which may be a metalnitride-silicon device (a conventional MOS having a very thin channel oxide and a nitride laye r deposited between the silicon channel and the device) has two threshold levels V TL , V TH  (Fig. 2). If the control electrode-source voltage Vgs is raised above a value + V REF  and returned to zero the transistor is switched to a threshold value of V TH  and if Vgs is lowered to a value below - V REF  then the transistor is switched to a threshold value of V TL . In operation the control electrode-source voltage must be greater than the threshold value before the transistor will conduct. The source of the transistor is defined as t hat electrode at an end of a conduction path that has the least positive potential. In operation of the matrix memory all transistor thresholds are set to V TH  by connecting all control electrodes to terminal 2, e.g. 20V and all row and column lines to terminal 1, e.g. ground (V RI  F  for instance is 12V). One or more selected transistors may then be reset to V TL  by connecting the row and column lines coupled to the selected transistors to terminal 2 and the selected control electrodes to terminal 1 and other lines are connected to terminal 1. Transistors connected to the rows and columns containing selected transistors thus have their control elec erodes connected to ground and have one row or column terminal coupled to terminal 2 and the other column or row terminal coupled to terminal 1. Since the source terminal is the terminal with theleast positive voltage each non- selected transistor has both source and control electrodes at ground potential. For readout the column conductors are coupled via a load resistor to terminal 3 ( + 5V), the control electrodes are coupled to terminal 3 and the row conductors are coupled to terminal 1. The voltage at terminal 3 is between V TL  and V REF  so the transistor conducts if its threshold is V TL  and does not conduct if its threshold is V TH . Each transistor is in direct contact with the substrate and removal of power supply does not cause loss of stored data (i.e. the memory is non- volatile).
