Sensing device for floating body cell memory and method thereof |
摘要 |
A memory device includes a memory array and a sense amplifier. The memory array includes a floating body cell configured to store a bit value. The sense amplifier includes a bit output configured to provide an output voltage representative of the bit value and a reference source configured to provide a reference voltage. The sense amplifier further includes a current mirror configured to provide a current to the first floating body cell based on the reference voltage, and a differential amplifier circuit configured to determine the output voltage based on the reference voltage and a voltage across the floating body cell resulting from application of the current to the floating body cell.
