ABSTRACT:
A frequency control circuit for an oscillator and a method therefor are disclosed and which frequency control circuit includes a flash cell having a cell transistor, a switching unit for outputting a first voltage to the flash cell in the program mode in accordance with an enable signal and outputting a second voltage in the read mode, a write driver for outputting a program voltage to the flash cell in the program mode in accordance with the enable signal, a bias unit for supplying a current to the flash cell in the read mode in accordance with the enable signal and generating a frequency control voltage which is proportional to a threshold voltage of the flash cell, and an oscillator for varying the frequency in accordance with the thusly generated frequency control voltage.
