latch
A digital logic circuit used to store one or more bits. A latch has a data
input, a clock input and an output. When the clock input is active, data on the
input is "latched" or stored and transfered to the output either immediately or
when the clock input goes inactive. The output will then retain its value until
the clock goes active again.
