ABSTRACT:
A biasing structure for a memory cell storage element, for setting an operating voltage at an accession electrode of the memory cell storage element. The biasing structure includes a biasing transistor coupled to the accession electrode and adapted to set the operating voltage based on a biasing voltage received at a control electrode of the biasing transistor, and a biasing voltage generator for generating the biasing voltage. The biasing voltage generator includes a feedback voltage regulation structure adapted track changes in a threshold voltage of the biasing transistor, so as to keep the operating voltage at the accession electrode of the memory cell storage element substantially stable against operating condition changes.
