WebCc 75 ff. The bitline and wordline have been stable at 2.5 V for a long time. The wordline sig- nal is shown in Fig. P8.13. What is the voltage stored on Cc before the wordline drops? Estimate the drop in voltage on the Cc due to coupling of the wordline signal through the gate-source capaci- - and tance. Use VTO 0.70 V, — 0.6 v. Word]ine voltage WebTo read a bit from a particular memory cell, the wordline along the cell's row is turned on, activating all the cells in the row. The stored value (Logic 0 or 1) from the cell then comes to the Bit-lines associated with it. The sense amplifier at the end of the two complementary bit-lines amplify the small voltages to a normal logic level.
