AS29LV800

Erase Suspend AS29LV800 allows interruption of sector erase operations to read data from or program data to asector not being erased. Erase suspend applies only during sector erase operations, including thetime-out period. Writing an Erase Suspend command during sector erase time-out results inimmediate termination of the time-out period and suspension of erase operation.AS29LV800 ignores any commands during erase suspend other than Read/Reset, Program or EraseResume commands. Writing the Erase Resume Command continueserase operations. Addresses areDon't Care when writing Erase Suspend or Erase Resume commands.

AS29LV800 takes 0.215 s to suspend erase operations after receiving Erase Suspend command.To determine completionof erase suspend, either check DQ6 after selecting an address of a sectornot being erased, or poll RY/BY. Check DQ2 in conjunction with DQ6 to determine if a sectorisbeing erased. AS29LV800 ignores redundant writes of Erase Suspend.

While in erase-suspend mode, AS29LV800 allows readingdata (erase-suspend-read mode) from orprogramming data (erase-suspend-program mode) to any sector not undergoing sectorerase;these operations are treated as standard read or standard programming mode. AS29LV800 defaultsto erase-suspend-readmode while an erase operation has been suspended.Write the Resume command 30h to continue operation of sector erase.AS29LV800 ignoresredundant writes of the Resume command. AS29LV800 permits multiple suspend/resumeoperations during sector erase.
