Overview
The IBM 04364ARLAC-6P is a static random-access memory (SRAM) integrated circuit with a total storage capacity of 4 megabits. The device is organized as 128K words by 36 bits, providing high-density data retention for legacy computing systems. It utilizes a surface-mount package configuration suitable for automated assembly processes in industrial and enterprise hardware environments.
Feature Summary
- Provides non-volatile-like rapid access speeds characteristic of SRAM technology
- Supports high-density data organization with 36-bit word width
- Designed for surface-mount integration into mainframe or server architectures
Applications
- Legacy IBM mainframe system memory expansion
- Enterprise server cache memory modules
- Industrial control system data buffering
Procurement Notes
Verify the exact manufacturer source when sourcing this component, as it may be available through authorized distributors or surplus suppliers like Rochester Electronics. Confirm the package type and pinout compatibility with your existing board design before procurement. Ensure the unit meets original equipment specifications for voltage and timing requirements to maintain system stability.
Selection Notes
Select this component specifically for systems requiring 128K x 36 bit SRAM configurations. It is suitable for applications where fast read/write cycles are critical and power consumption must be managed within standard logic levels. Consider availability constraints as this is a specialized legacy part rather than a mass-market consumer item.
Part Context
This part belongs to IBM's historical line of memory integrated circuits used in mid-range and large-scale computing infrastructure. It represents a specific generation of SRAM technology designed to support the memory demands of enterprise servers and mainframes during its production era. The component is distinct from modern volatile memory technologies due to its specific architecture and interface.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical compatibility and pinout alignment if considering alternative SRAM devices from other manufacturers.
