A circuit including an oscillator circuit, a current generator circuit and a voltage generator circuit. The oscillator circuit may be configured to generate an output signal having a frequency in response to (i) a first control signal and (ii) a second control signal. The current generator may be configured to generate said first control signal in response to a first adjustment signal. The voltage generator circuit may be configured to generate the second control signal in response to a second adjustment signal.

Programmable oscillator scheme

An oscillator circuit configured to generate an output signal having a frequency comprising a current source, a trim circuit, and one or more capacitors. The current source may be configured to generate a temperature independent current in response to a first adjustment signal. The trim circuit may be configured to generate the first adjustment signal. The one or more capacitors may be configured to charge to a controlled voltage using the temperature independent current. The controlled voltage may regulate a variation of the frequency of the output signal.

A circuit comprising a memory array having a first region, a second region, a plurality of bitlines and an X-decoder. A plurality of transistors may each coupled between the first and second regions, where each of the transistors may be configured to (i) separate the first and the second region during a read operation and (ii) join the first and the second region during a write operation. Alternatively, a plurality of memory regions may be implemented, each separated by another plurality of transistors.
