Patent ID: 8873321

Claim:
A method comprising: causing a first data line and a second data line to have a data voltage level; causing a first power supply line and a second power supply line of a sense amplifier to have a power supply voltage level; causing a data split between the first data line and the second data line to develop; and performing at least one of the following steps: causing the first power supply line to rise towards a first power supply voltage value, and when the first power supply line reaches a first predetermined voltage value, causing the first power supply to rise above the first power supply voltage value; and causing the second power supply line to fall towards a second power supply voltage value, and when the second power supply line reaches a second predetermined voltage value, causing the second power supply line to fall below the second power supply voltage value, wherein at least one of the following conditions is met; causing the first power supply line to rise above the first power supply voltage value includes charging a first capacitive device coupled to the first power supply line; or causing the second power supply line to fall below the second power supply voltage value includes charging a second capacitive device coupled to the second power supply line.
