2.4
Asynchronous Read
[Disclaimer]
A20 input shown in timing diagrams is not used in 16Mbit CellularRAM. Should be “don’t care”.
The CellularRAM applies the standard asynchronous SRAM protocol to perform read and write accesses.
Reading from the device in asynchronous mode is accomplished by asserting the Chip Select (CS1) and Output
Enable (OE) signals to low while forcing Write Enable (WE) to high. If the Upper Byte (UB) control line is set active
low then the upper word of the addressed data is driven on the output lines, DQ15 to DQ8. If the Lower Byte (LB)
control line is set active low then the lower word of the addressed data is driven on the output lines, DQ7 to DQ0.
