Method and apparatus processing variable resistance memory cell write operation

Image Number 2 for United States Patent #7295462.

A circuit and method for writing to a variable resistance memory cell. The circuit includes a variable resistance memory cell, a switchable current blocking device and a charge storing element. As the switchable current blocking device blocks current flow through the variable resistance memory cell, the charge storing element charges. When the switchable current blocking device is not blocking current, the charge storing element discharges through the variable resistance memory cell, generating a write current sufficient to write high resistance variable resistance memory cells.
