A.3.1.13
The maximum set field margin level time is given by:
A.3.1.14
The time required to Erase Verify D-Flash for a given number of words N
A.3.1.15
D-Flash programming time is dependent on the number of words being programmed and their location
with respect to a row boundary since programming across a row boundary requires extra steps. The D-
Flash programming time is specified for different cases: 1,2,3,4 words and 4 words across a row boundary.
The typical D-Flash programming time is given by the following equation, where N
of words; BC=0 if no row boundary is crossed and BC=1 if a row boundary is crossed:
The maximum D-Flash programming time is given by:
A.3.1.16
Typical D-Flash sector erase times, expected on a new device where no margin verify fails occur, is given
by:
Maximum D-Flash sector erase times is given by:
The D-Flash sector erase time is ~5ms on a new device and can extend to ~20ms as the flash is cycled.
