Abstract
The presented material on current sensing is not limited to embedded SRAM. It can be adapted to any array-like structure. Beside various memory types, this includes CMOS camera chips [117]. Due to its excellent speed in the presence of large input capacitances, current sense amplifiers can also be used as receivers for signal transmission along highly capacitive busses [35, 49]. Beside speed, another advantage is important for read-only memory (ROM). Depending on the data contents a ROM bitline can become floating and, hence, become very sensitive to capacitive coupling and crosstalk. Since current sensing establishes a low input impedance, it prevents the bitlines from being floating. As it suppresses a bitline voltage swing, it also eliminates coupling from adjacent bitlines.
