Rangarao Samineni is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of memory circuit design, holding 2 patents that showcase his innovative approach to improving memory performance.

Latest Patents

One of his latest patents is titled "Sense amplifier architecture providing improved memory performance." This invention presents a sense amplifier for a memory circuit that reduces sensing times by introducing a local reference generator. The design includes two capacitors that are pre-charged before a sensing operation. The first capacitor discharges through a selected memory cell at a rate dependent on the conductivity of that cell. After a sensing interval, the voltage level on the first capacitor is compared with that of the second capacitor to determine the result of the sensing operation.

Another significant patent is "Temperature independent reference current generation for calibration." This patent discloses techniques for generating a temperature-independent reference current, which can be utilized during calibration. The current is generated based on a current through an on-chip calibration resistor, eliminating the need for an off-chip calibration resistor, which can be costly and slow. The voltage at one terminal of the on-chip calibration resistor is modulated to cancel the temperature coefficient, resulting in a temperature-independent current.
