Bit Capacitance Solution

Follow our step by step solution on how to calculate Bit Capacitance?

FIRST Step Consider the formula

C bit = (\frac{V dd \cdot C cell}{2 \cdot ΔV}) - C cell

Next Step Substitute values of Variables

∴

C bit = (\frac{2.58V \cdot 5.98pF}{2 \cdot 0.42V}) - 5.98pF

Next Step Convert Units

∴

C bit = (\frac{2.58V \cdot 6E-12F}{2 \cdot 0.42V}) - 6E-12F

Next Step Prepare to Evaluate

∴

C bit = (\frac{2.58 \cdot 6E-12}{2 \cdot 0.42}) - 6E-12

Next Step Evaluate

∴

C bit = 1.23871428571429E-11F

Next Step Convert to Output's Unit

∴

C bit = 12.3871428571429pF

LAST Step Rounding Answer

∴

C bit = 12.3871pF

How to Evaluate Bit Capacitance?

Bit Capacitance evaluator uses Bit Capacitance = ((Positive Voltage*Cell Capacitance)/(2*Voltage Swing on Bitline))-Cell Capacitance to evaluate the Bit Capacitance, The Bit Capacitance formula is represented as CB. It is calculated as the capacitance of the bit line per unit length. Memory cells are etched onto a silicon wafer in an array of columns (bit lines) and rows (word lines). Bit Capacitance is denoted by C_bit symbol.

How to evaluate Bit Capacitance using this online evaluator? To use this online evaluator for Bit Capacitance, enter Positive Voltage (V_dd), Cell Capacitance (C_cell) & Voltage Swing on Bitline (ΔV) and hit the calculate button.

FAQs on Bit Capacitance

What is the formula to find Bit Capacitance?
