• Description: STACKED MULTI CHIP PRODUCT FLASH MEMORY AND RAM
• Manufacturer: SPANSION [SPANSION]

Notes:
1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector
2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5.

being erased. During chip erase, a valid address is any non-protected sector address.
RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Al-
gorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final
WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY#
pins can be tied together in parallel with a pull-up resistor to V
If the output is low (Busy), the device is actively erasing or programming. (This includes pro-
gramming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read
mode, the standby mode, or in the erase-suspend-read mode.
