DEPTH EXPANSION —
IDT2801/72811/72821/72831/
72841 can be adapted to applications that require greater than
256/512/1024/2048/4096 words. The existence of double
enable pins on the read and write ports allow depth expansion.
The Write Enable 2/Load (WENA2, WENB2) pins are used as
a second write enables in a depth expansion configuration,
thus the Programmable flags are set to the default values.
Depth expansion is possible by using one enable input for
system control while the other enable input is controlled by
expansion logic to direct the flow of data. A typical application

would have the expansion logic alternate data access from
one device to the next in a sequential manner. The IDT2801/
72811/72821/72831/72841 operates in the Depth Expansion
configuration when the following conditions are met:
1. WENA2/
LDA
and WENB2/
LDB
pins are held HIGH dur-
ing Reset so that these pins operate as second Write Enables.
2. External logic is used to control the flow of data.
Please see the Application Note" DEPTH EXPANSION OF
IDT'S SYNCHRONOUS FIFOs USING THE RING COUNTER
APPROACH" for details of this configuration.
