Abstract
The apparatus provided may be a memory circuit. The memory circuit includes a memory cell. The memory cell has a bitline. The memory circuit also includes a write driver. The write driver is configured to drive the bitline to write a bit to the memory cell during a write operation. The write driver is also configured to float the bitline to mask the bit during a read operation. The write driver may use NMOS pullup transistors.
