Sony patents memory cell design with added resistor for better stability
Sony has been granted a patent for a specific layout of memory cells used in electronic devices. The design connects two inverters in a loop and adds a transistor and resistor to help control the electrical signal stored in the cell.
In the filing’s own words
An operation device according to an embodiment of the present disclosure includes a memory cell array including multiple memory cells. The multiple memory cells each include a first inverter including a first input unit and a first output unit, a second inverter including a second input unit coupled to the first output unit and a second output unit coupled to the first input unit and outputting a first signal, a first transistor to which the first signal is inputted from the second output unit, and a resistor coupled in series to the first transistor.
What exactly they claim (claim 1)
1. An operation device comprising a memory cell array including multiple memory cells, the multiple memory cells each including: a first inverter including a first input and a first output; a second inverter including a second input coupled to the first output and a second output coupled to the first input, the second output outputting a first signal; a first transistor to which the first signal is inputted from the second output; and a resistor coupled in series to the first transistor, wherein the first transistor has a gate coupled to the first output, and the resistor is coupled to a source or a drain of the first transistor.
