Hi. A ">=1" gate means a OR gate. The european symbol. Takes less effort to draw manually.
Thanks. I agree this sound more like a reasonable term.
Still, searching for "basic memory latch" on the net still doesn't returns any images that looks like this schematic. I tried all the biggest search engines out there, and they all returned a lot of images of the well known SR flip flop (the one where upper and lower part is horisontally mirrored along the middle).
