DESCRIPTION
The DS2016 2k x 8 3V/5V Operation Static RAM is a 16,384-bit, low-power, fully static random access
memory organized as 2048 words by 8 bits using CMOS technology. The device operates from a single
power supply with a voltage input between 2.7 and 5.5 volts. The chip enable input (
CE
) is used for
device selection and can be used in order to achieve the minimum standby current mode, which facilitates
both battery operated and battery backup applications. The device provides access times as fast as 100 ns
when operated from a 5-volt power supply input and also provides relatively good performance of 250 ns
access while operating from a 3-volt input. The device maintains TTL-level inputs and outputs over the
input voltage range of 2.7 to 5.5 volts. The DS2016 is most suitable for low-power applications where
battery operation or battery backup for nonvolatility is required. The DS2016 is a JEDEC-standard 2k x 8
SRAM and is pin-compatible with ROM and EPROM of similar density.
