GENERAL DESCRIPTION  
The Am27C256 is a 256-Kbit, ultraviolet erasable pro-  
grammable read-only memory. It is organized as 32K  
words by 8 bits per word, operates from a single +5 V  
supply, has a static standby mode, and features fast  
single address location programming. Products are  
available in windowed ceramic DIP packages, as well  
as plastic one time programmable (OTP) PDIP and  
PLCC packages.  
thus eliminating bus contention in a multiple bus micro-  
processor system.  
AMD’s CMOS process technology provides high  
speed, low power, and high noise immunity. Typical  
power consumption is only 80 mW in active mode, and  
100 µW in standby mode.  
All signals are TTL levels, including programming sig-  
nals. Bit locations may be programmed singly, in  
blocks, or at random. The device supports AMD’s  
Flashrite programming algorithm (100 µs pulses), re-  
sulting in a typical programming time of 4 seconds.  
Data can be typically accessed in less than 55 ns, al-  
lowing high-performance microprocessors to operate  
without any WAIT states. The device offers separate  
Output Enable (OE#) and Chip Enable (CE#) controls,
