Methods, systems, and devices for power switching for embedded memory are described. A system may be configured with circuitry (e.g., power supply switching circuitry) coupled with or between a power supply and a power input node of a memory device, which may support selectively coupling or isolating the memory device and the power supply based on various conditions. For example, the circuitry may be configured for a selective coupling or a selective isolation based on a voltage level of the power supply satisfying various voltage thresholds. The circuitry may also be configured to support various input or output signaling, such as transmitting an indication of an isolation from the power supply, transmitting an indication to perform a memory initialization, or receiving an indication or command to perform a power cycle.
