Power Supply Decoupling
Flash memory devices require careful power supply de-coupling. Three basic power supply current
considerations are: 1) standby current levels; 2) active current levels; and 3) transient peaks
produced when CE# and OE# are asserted and deasserted.
When the device is accessed, many internal conditions change. Circuits within the device enable
charge-pumps, and internal logic states change at high speed. All of these internal activities
produce transient signals. Transient current magnitudes depend on the device outputs’ capacitive
and inductive loading. Two-line control and correct de-coupling capacitor selection suppress
transient voltage peaks.
Because Intel
Multi-Level Cell (MLC) flash memory devices draw their power from V
CC
, VPP,
and VCCQ, each power connection should have a 0.1 μF ceramic capacitor to ground. High-
frequency, inherently low-inductance capacitors should be placed as close as possible to package
leads.
Additionally, for every eight devices used in the system, a 4.7 μF electrolytic capacitor should be
placed between power and ground close to the devices. The bulk capacitor is meant to overcome
voltage droop caused by PCB trace inductance.
