57 / 66 page  February 1, 2007 26190C8 Am29LV640MT/B 55 D A TA SH EET AC CHARACTERISTICS Alternate CE# Controlled Erase and Program Operations Notes: 1. Not 100% tested. 2. See Erase And Programming Performance on page 57 for more information. 3. For 1–16 words programmed/1–32 bytes programmed. 4. Effective write buffer specification is based upon a 16-word/32-byte write buffer operation. 5. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the write buffer. 6. When using the program suspend/resume feature, if the suspend command is issued within t POLL, tPOLL must be fully re-applied upon resuming the programming operation. If the suspend command is issued after tPOLL, tPOLL is not required again prior to reading the status bits upon resuming.
