The Am2764A, Am27128A, and the Am27256 are One- Time Programmable Read-Only Memories (OTPROMS) and are organized as 8 bits per word. The plastic OTPROMs are ideal for volume production, First, because they can be inventoried unprogrammed and used with current-level software revisions, second, there is no window to be covered to prevent light from changing data - this could eliminate a manufacturing step and increase the reliability of the system; and third, they are compatible with auto insertion equipment. All standard OTPROMs offer access times of 250 ns, allowing operation with high-speed microprocessors without any Wait states. Some of AMD's OTPROMs have access times of as fast as 200 ns. To eliminate bus contention on a multiple-bus microprocessor system, all AMD OTPROMs offer separate output enable (OE) and chip enable (CE) controls. All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in blocks, or at random. To reduce programming time, AMD's OTPROMS may be programmed using the Flashrite programming algorithm, which offers several fold improvement in programming time.Advanced Micro Devices, Inc. (AMD) is an American multinational corporation and fabless semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. AMD was founded in 1969 by Jerry Sanders and a group of other technology professionals. The company's early products were primarily memory chips and other components for computers. In 1975, AMD entered the microprocessor market, competing with Intel, its main rival in the industry. In the early 2000s, it experienced significant growth and success, thanks in part to its strong position in the PC market and the success of its Athlon and Opteron processors.Your shipment will arrive via USPS Priority Mail (1-4 business days) or USPS Ground Advantage (2-5 business days), after the 2-3 day processing time (upon paid purchase)Shipment(s) sent out of Lemon Grove, California, USAWill be packed very well - read our feedback!No Returns ***AN INVOICE WILL BE SENT AFTER PURCHASE, WHICH MAY REFLECT A MORE ACCURATE POSTAGE RATE FOR THIS ITEM - DON'T PASS THIS UP YET!
