8Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
512K × 16 bit
Overview
Features
The N08M1618L1A is an integrated memory
device intended for non life-support medical
applications. This device is a 8 megabit memory
organized as 524,288 words by 16 bits. The device
is designed and fabricated using AMI
• Dual voltage for Optimum Performance:
Vccq - 2.3 to 3.6 Volts
Vcc - 1.4 to 2.2 Volts
• Very low standby current
0.5µA at 1.8V and 37 deg C
Semiconductor’s advanced CMOS technology with
reliability inhancements for medical users. The
device operates with two chip enable (CE1 and
CE2) controls and output enable (OE) to allow for
easy memory expansion. Byte controls (UB and
LB) allow the upper and lower bytes to be
• Very low operating current
1.0mA at 1.8V and 1µs (Typical)
• Very low Page Mode operating current
0.5mA at 1.8V and 1µs (Typical)
• Simple memory control
accessed independently and can also be used to
deselect the device. This device is optimal for
various applications where low-power is critical
such as battery backup and hand-held devices.
The device can operate over a very wide
