scope:

This specification covers the detail requirements for monolithic silicon, dynamic, CMOS, 1,048,576/1-bit random access memory microcircuits. Two product assurance classes (S and B), four electrical performance categories and five case styles are provided and are reflected in the complete part number.

The part or identifying number shall be in accordance with MIL-M-38510, and as specified herein.

The device types shall be as shown in the following:

Device Device Temperature Access/cycle Refresh type organization range (case) time interval 01 1,048,576/1-bit RAM −55°C to +125°C 80/160 ns 8 ms 02 1,048,576/1-bit RAM −55°C to +125°C 100/200 ns 8 ms 03 1,048,576/1-bit RAM −55°C to +125°C 120/230 ns 8 ms 04 1,048,576/1-bit RAM −55°C to +125°C 150/260 ns 8 ms

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outlines shall be designated as follows:
