Using a precharge characteristics of a node to validate a previous data/signal value represented by a discharge of said node

Apparatus for processing data comprising:

• discharging means for selectively discharging a node from a precharge voltage during a discharge phase to represent a data value;
• precharging means for precharging said node to said precharge voltage during a precharge phase;
• sensing means for detecting during said discharge phase a discharge characteristic of said discharge to determine said data value;
• and
• validation means for detecting during said precharge phase a precharge characteristic of said precharge and for comparing said discharge characteristic to said precharge characteristic to identify an operation error when said discharge characteristic does not match said precharge characteristic.

A method of operating an Apparatus for processing data comprising the steps of:

• selectively discharging a node from a precharge voltage during a discharge phase to represent a data value;
• precharging said node to said precharge voltage during a precharge phase;
• detecting during said discharge phase a discharge characteristic of said discharge to determine said data value;
• detecting during said precharge phase a precharge characteristic of said precharge;
• and
• comparing said discharge characteristic to said precharge characteristic to identify an operation error when said discharge characteristic does not match said precharge characteristic.
