MSR820AJC288-12

Memory IC Overview

The MSR820AJC288-12 is a Bandwidth Engine (BE2-RMW) from the BLAZAR family, providing 576 Mb of high-speed SRAM memory. It features a 3.2 ns tRC access time and supports up to 3.3 billion transactions per second with a peak single-chip bandwidth of 320 Gb/s. The device utilizes a high-efficiency serial GCI interface, typically requiring 32 pins for standard operation, which significantly reduces I/O pin count compared to parallel alternatives. It includes optional In-Memory Functions such as BURST and Read/Modify/Write operations.

Memory IC Feature Summary

• Integrates optional In-Memory Functions including sequential BURST and computational Read/Modify/Write operations directly within the memory array.
• Employs a high-speed serial GCI interface that minimizes pin count while maintaining high bandwidth and signal integrity over connectors.
• Provides an RTL memory controller that abstracts the serial interface, presenting a transparent parallel QDR-like interface to user logic.

Memory IC Applications

• Network search and traffic monitoring
• Security firewall and anomaly detection
• Genomics and AI random forest processing

Memory IC Procurement Notes

Verify the specific suffix 'JC288' against official MoSys documentation to confirm package type and temperature range. Ensure compatibility with the required RTL controller version for your FPGA platform. Confirm lead times and availability directly with authorized distributors as this component may be subject to supply constraints.

Memory IC Selection Notes

Select this device when high capacity and high bandwidth are required in a compact footprint. It serves as a direct replacement for multiple QDR or SyncSRAM devices. Consider the optional In-Memory Functions if application logic involves frequent data movement or simple arithmetic operations to reduce host processor load.

Memory IC Part Context

The MSR820AJC288-12 belongs to the BLAZAR family of Accelerator Engines, specifically the Bandwidth Engine 2 (BE2) series. This family is designed to address memory bottleneck challenges by combining high-density memory with embedded acceleration capabilities, offering a scalable solution for high-performance computing applications.

Memory IC Replacement Considerations

The datasheet indicates pin compatibility with the MSP220 (QPR4). It can replace four 144Mb QDR devices. Verify electrical parameters and interface timing against existing designs before substitution.
