GENERAL INFORMATIONThe SGS-THOMSON Microelectronics Memoriesdata book is a comprehensive collection of informationon advanced, high density, high speed memoryproducts for specific applications.SGS-THOMSON offers 4 groups of memory products:EPROMs and OTP's, EEPROMs, ROMs andStatic RAMs.EPROMs (Electrically Programmable Read OnlyMemory) and OTP's (One Time ProgrammableRead Only Memory) are non volatile memory componentsfor program storage.SGS-THOMSON Microelectronics has one of thelargest product range to meet your requirements:- all densities from 16K to 1 Megabit.- NMOS or CMOS technology.- Jedec approved footprints for easy upgrades.- UV EPROM in Cerdip package.- One Time Programmable in windowless plasticpackage ideally suited for high volume productionenvironment and surface mounting applications.- very fast programming algorithm.EEPROMS (Electrically Erasable ProgrammableRead Only Memories) embody the fOil range ofEPROM functional advantages plus the added featuresof in-circuit erasability and programmability.SGS-THOMSON range comprehends serial accesspr~ucts, with densities ranging from 256 bit to 2Kbit, including 2-wire bus compatible versions.Static RAM products cover high speed memories,biport devices and Zeropower TimekeeperTMRAMS.• High speed memories with a device density rangeof 4Kbits to 64Kbits and performance from20ns to 55ns.Organizational flexibility (4K x 1, 16K x 1, 4K x 4,64K x 1, 8K x 8) covers a vast range of applications,including large mainframes, high speedcontrollers, communications, graphics displayand workstations.• Biport devices consist of a family of FIFO (First­In-First-Out) buffers. These FIFO's provide an interfacebetween digital information paths with widelyvarying speeds. Each information sourcecan thus operate at its own intrinsic speed, whileresults are processed or distributed at speedsfrom 25ns to ~OOns. The Biport family also includesa range of veritable Dual Port Rams enablingapplications in systems with two or moreprocessors, or with distributed processors, whereseparate computing units must exchange dataat speeds approaching real time.• The Zeropower and Timekeeper RAM familycombines the operating simplicity of conventionbyte-wide SRAM's with the excellent data integrityof Zeropower technology. This integrity isachieved thanks to the use of advanced CMOStechnology and long-life lithium cells. With densitiesfrom 2K x 8 to 8K x 8 and access/cycle timesup to 120ns (150ns for 8K x 8), SGS­THOMSON Zeropower RAMs cover the full rangeof non-volatile needs for all microprocessorbased systems. Thanks to the combined featuresof Zeropower technology with an on-chip realtime clock, the 48T02 Timekeeper offers unparallelednon-volatile performance.9
