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 2.7V and 5.5V. The chip enable input (
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 100ns when
operated from a 5V power supply input and also provides relatively good performance of 250ns access
while operating from a 3V input. The device maintains TTL-level inputs and outputs over the input
voltage range of 2.7V to 5.5V. 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.
