Abstract
A sense amplifier circuit can be coupled to a match line for receiving a match line voltage and to a low potential line for receiving a low potential voltage from a memory array. The sense amplifier circuit can include a charging circuit coupled between a power supply voltage and the match line voltage that comprises no p-channel transistors. A discharging circuit can be coupled between the low potential voltage and a ground supply voltage. An n-channel sensing device can coupled to detect a potential difference between the match line voltage and the low potential voltage.
