MSR622AJC288-12

Memory IC Overview

The MSR622AJC288-12 is a Bandwidth Engine (BE2) Accelerator Engine featuring 576 Mb of SRAM organized as 8M x 72b. It supports up to 3.3 billion transactions per second with a 3.2 ns tRC access time and achieves single-chip bandwidth of up to 320 Gbps throughput. The device utilizes a high-speed serial interface with the GCI protocol, typically employing 8 lanes or 32 pins for operation. It includes optional In-Memory Functions such as BURST and Read/Modify/Write operations.

Memory IC Feature Summary

• Provides high-capacity memory on a single device that replaces multiple traditional QDR or SyncSRAM memories.
• Features an efficient serial transport command and data protocol optimized for high bandwidth and signal integrity.
• Includes optional In-Memory Functions like BURST for sequential data movement and RMW for compute operations.
• Offers a transparent parallel QDR-like interface via MoSys-supplied RTL controllers for simplified FPGA integration.

Memory IC Applications

• Network search and firewall applications requiring high bandwidth data access
• FPGA acceleration for Xilinx and Intel platforms
• Real-time statistics buffering and traffic monitoring
• Security anomaly detection and genomics processing

Memory IC Procurement Notes

Verify the specific suffix codes against official documentation to confirm pin compatibility and functional variations within the Blazar family. Ensure the design utilizes the provided RTL controller for proper interface management. Confirm that the application requirements align with the BE2 architecture specifications before procurement.

Memory IC Selection Notes

Select this component for applications needing high capacity and speed where low latency is critical. It serves as a direct replacement for multiple QDR devices, reducing board space and pin count. Consider the optional In-Memory Functions if sequential data movement or read-modify-write operations are required to accelerate performance.

Memory IC Part Context

The MSR622AJC288-12 belongs to the BLAZAR Family of Accelerator Engines, specifically the Bandwidth Engine (BE2) series. This family is designed to solve memory bottleneck challenges by providing high-speed random access and embedded in-memory functions. The BE2 variant focuses on slower speed applications needing high capacity compared to the higher-speed BE3 models.

Memory IC Replacement Considerations

The MSR622 is pin-compatible with the MSP220 (QPR4). It can replace four QDR type memories or SyncSRAM devices. Designers should account for the reduction in I/O pins and the need for appropriate RTL controllers when migrating from traditional parallel memory architectures.
