  • Bit cell internal voltage control
    Patent number: 8947953
    Abstract: Among other things, techniques for facilitating a write operation to a bit cell are provided. A pulse generator initializes lowering of an internal voltage level associated with a bit cell that is to be written to by a write operation. In this way, the bit cell is placed into a writeable voltage state, such that a potential of the bit cell can be overcome by the write operation. A voltage detector sends a reset signal to the pulse generator based upon the pulse generator lowering the internal voltage level past a reset trigger level. Responsive to receiving the reset signal, the pulse generator initializes charging of the internal voltage level to an original voltage level. In this way, the lowering of the internal voltage level is controlled so that one or more other bit cells are not affected (e.g., suffer data retention failure) by the relatively lower internal voltage level.
