Abstract
A selection circuit for a bipolar ECL memory having memory cell connected to cell selection lines and, more particularly, to upper and lower wordlines. The circuit includes a line driver connected to the upper wordline, an input stage for controlling the line driver to activate the upper wordline connected thereto in response to an address signal, and a switching device responsive to the input stage for applying a discharging current to the lower word line to speed up deactivation of the memory cell in response to a change in the address signal. In one embodiment, the line driver is also turned on at an increased rate for a limited time following application of the address signal to speed up the activation of the line.
