Overview
The IBM 0436A11QLAA-4 is a static random-access memory (SRAM) integrated circuit with a total storage capacity of 1 megabit. It operates using Low Voltage Transistor-Transistor Logic (LVTTL) interface standards, ensuring compatibility with specific logic voltage levels required for data integrity in legacy or specialized computing environments. The component is housed in a 119-ball Ball Grid Array (BGA) package, featuring physical dimensions of 17mm by 7mm. This configuration supports high-density mounting on printed circuit boards while maintaining signal integrity through the grid array connection method.
Feature Summary
- Utilizes LVTTL interface for standardized logic level communication
- Provides 1Mbit SRAM storage capacity for volatile data retention
- Encapsulated in a compact 119-ball BGA form factor
Applications
- IBM System x3650 M4 server memory subsystems
- IBM Power E1150 enterprise server memory modules
- Memory-intensive enterprise workload processing units
Procurement Notes
Verify the manufacturer part number 0436A11QLAA-4 against official IBM documentation to ensure authenticity. Confirm that the LVTTL voltage specifications match your system requirements. Check for RoHS compliance status if environmental regulations apply to your deployment. Ensure the BGA package condition is free from physical damage before installation.
Selection Notes
Select this component when integrating with IBM hardware platforms requiring 1Mbit SRAM buffers. Ensure the design supports LVTTL signaling levels and accommodates the 17x7mm BGA footprint. Consider thermal management capabilities inherent to the BGA package type during PCB layout planning.
Part Context
This SRAM IC is utilized within IBM's enterprise server infrastructure, specifically supporting memory architectures in systems like the System x3650 M4 and Power E1150. These servers handle data-intensive tasks, requiring reliable volatile memory components for temporary data storage and processing acceleration within the server's memory hierarchy.
Replacement Considerations
No publicly confirmed substitute part numbers are available for this specific IBM component. Direct replacement requires sourcing identical IBM-manufactured units to maintain system compatibility and performance specifications.
