Various embodiments of methods and systems for adaptive thermal management techniques implemented in a portable computing device (“PCD”) are disclosed. Notably, in many PCDs, temperature thresholds associated with various components in the PCD such as, but not limited to, die junction temperatures, package on package (“PoP”) memory temperatures and the “touch temperature” of the external surfaces of the device itself limits the extent to which the performance capabilities of the PCD can be exploited. It is an advantage of the various embodiments of methods and systems for adaptive thermal management that, when a temperature threshold is violated, the performance of the PCD is sacrificed only as much and for as long as necessary to clear the violation before authorizing the thermally aggressive processing component(s) to return to a maximum operating power.

An INVSRC node and a SAREF node are previously precharged. After a potential on a bit line is reset, the bit line (BLS node) is precharged. In this event, a clamp MOS transistor in a sense amplifier is in ON state, and an SA node is also precharged simultaneously. A precharge level is set to a value lower than a threshold voltage of an inverter. Subsequently, when SAEN transitions to “H,” a sense operation is performed. For reading data “0,” the SA node is rapidly increased to Vdd. For reading data “1,” the SA node slowly approaches to Vss. A change in the potential at the SA node is detected by the inverter.
