Method for concurrently programming or accessing a plurality of in-system-programmable logic devices

摘要: An improved method for concurrently programming in-system programmable logic devices (PLDs). More specifically, where within a plurality of serially connected PLDs, there are having different numbers memory cells, and whose cells require wait periods to carry out programming, the herein provides more optimum time efficiency uses significantly less overall erasing or reading back PLDs. Also, invention accommodates implementation retries assure complete even when initial attempt is not entirely successful. The steps accommodating PLDs with times by bypassing fully programmed speeding up after smaller slower larger faster still programmed. employs step altering program from concurrent sequential optimize retry efficiency.
