A memory circuit is provided comprising a memory cell, a pair of conducting lines operable to signal the logic state of the memory cell and read circuitry operable to perform a read operation by detecting a voltage level of at least one of the pair of conducting lines. The memory circuit comprises a pull-down circuit having an on configuration in which it is operable to pull-down a voltage level of at least one of the pair of conducting lines so as to affect the read operation and an off-configuration in which the pull-down circuit cannot affect the read operation. Control circuitry is provided to control whether the pull-down circuit is in the on configuration or the off configuration. The memory circuit can be incorporated in a data processing apparatus and a method of operating a memory circuit is provided in which a pull-down circuit is controlled to be in an on configuration or in an off configuration.
