Overview
The TMS44100-80DJ is a 4,194,304-word by 1-bit dynamic random-access memory (DRAM) manufactured by Texas Instruments. It operates with an access time of 80 nanoseconds and supports asynchronous operation modes including fast page access. The device utilizes RAS-only refresh, CAS-before-RAS refresh, and hidden refresh capabilities to maintain data integrity. It is housed in a ceramic dual in-line package designed for high-reliability applications.
Feature Summary
- Supports fast page mode for efficient sequential data access
- Provides multiple refresh options including RAS-only and hidden refresh
- Constructed with ceramic packaging for enhanced durability
Applications
- High-reliability computing systems requiring robust memory storage
- Industrial control environments utilizing asynchronous DRAM architectures
- Military or aerospace electronic systems demanding ceramic-packaged components
Procurement Notes
Verify the specific suffix DJ indicates the correct package variant and temperature rating against official Texas Instruments documentation. Confirm that the component meets all necessary environmental compliance standards required for your specific deployment context before procurement.
Selection Notes
Select this component when a 1-bit wide, 4M-depth asynchronous DRAM is required. Ensure the system design accommodates the specific timing requirements of 80ns access and the power management needs associated with dynamic RAM refresh cycles within the specified operating temperature range.
Part Context
