AM29DL640D Datasheet 64 Megabit CMOS 3.0 Volt-only / Simultaneous Read/Write Flash Memory

Manufacturer: AMD

Overview: ADVANCE INFORMATION Am29DL640D 64 Megabit (8 M x 8-Bit/4 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES s Simultaneous Read/Write operations — Data can be continuously read from one bank while executing erase/program functions in another bank. — Zero latency between read and write operations s FlexBank architecture — Read may occur in any of the three banks not being written or erased. — Four banks may be grouped by customer to achieve desired bank divisions. s Manufactured on 0.23 µm process technology s SecSi™ (Secured Silicon) Sector: Extra 256 Byte sector — Factory locked and identifiable: 16 bytes available for secure, random factory Electronic Serial Number; verifiable as factory locked through autoselect function. ExpressFlash option allows entire sector to be available for factory-secured data — Customer lockable: Can be read or programmed just like other sectors. Once locked, data cannot be changed s Zero Power Operation — Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero.
