A 4.2 Gb/S $5^{\text {th }}$ Generation F-Chip of Toggle 5.1 Specification With All-Path Speed Boosting Scheme and Sca Protocol for High Density Nand Flash Applications
This paper introduces a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$4.2 ~\text{Gb} / \mathrm{s} 5^{\text {th }}$</tex> generation F-chip operating at a 1.1 V supply voltage. To achieve high-speed performance even in high-capacity memory packages, a speed boosting scheme is proposed to ensure optimal write and read performance. This scheme includes technologies for correcting the duty cycle, offset and skew of DQ and DQS signals. To mitigate leakage in the devices, a power gating technique with whole of chip is also introduced. Also, a SCA converter design is presented to overcome command speed bottlenecks for improvement of I/O efficiency. This proposed work achieves a 37 % reduction in energy/bit, with a 1.4 x speed improvement, and a 92 % reduction in standby current through power gating.
