ABSTRACT:
An integrated circuit (10) includes a memory (20) which has a plurality of memory modes, including a high density memory mode and a high speed/reliability memory mode. The high speed/reliability memory mode may alternately be used as a high reliability memory mode. Memory (20) includes a configuration circuit (80) which selects one of the plurality of memory modes. Configuration circuit (80) provides configuration information to sense amplifier control circuit (72). Sense amplifier control circuit (72) provides control information to sense amplifiers (70) in order to place sense amplifiers (70) in one of a plurality of operating modes. In one embodiment, the plurality of operating modes of sense amplifiers (70) includes a complementary differential operating mode and a referenced differential operating mode.
