A latch circuit for retaining and transmitting an input data value is disclosed, along with a memory, and a method for retaining and transmitting data. The latch circuit comprises: a primary input for receiving a data value; an output for outputting the data value; a data transmission path comprising a transmitting device for transmitting the data value from the primary input to the output; a feedback loop for retaining the data value, the feedback loop comprising the transmitting device and a further device, the further device being configured to turn on in response to assertion of an activating signal and to turn off in response to no assertion of the activating signal, the feedback loop not retaining data when the further device is turned off; the feedback loop further comprising a multiplexer, the multiplexer being configured to connect either the data transmitting device to the further device and form the feedback loop or to connect a secondary input to the further device and form a secondary data transmission path from the secondary input through the further device and the transmitting device to the output.
