CPC G11C 16/30 (2013.01) [G06F 1/28 (2013.01); G06F 1/3296 (2013.01); G11C 5/14 (2013.01)] | 20 Claims |
1. An apparatus, comprising:
an array of memory cells;
a pin for providing output of loopback information based at least in part on a loopback setting of the apparatus;
a capacitive component coupled with the pin for communicating an alternating current (AC) signal at the pin; and
a controller operable to cause the apparatus to:
determine that the loopback setting indicates that the apparatus is operating in a mode different than a loopback mode;
set the pin to an inactive state based at least in part on determining that the apparatus is operating in the mode different than the loopback mode;
determine, after setting the pin to the inactive state, that a supply voltage for the array of memory cells is outside a target range associated with the supply voltage; and
generate the AC signal at the pin based at least in part on determining that the supply voltage is outside the target range.
