OVERVIEW

The Single-Port SRAM Controller serves as a critical memory interface within system-on-chip (SoC) architectures, designed to provide high performance, low-latency access to on-chip or external single-port SRAM devices. Its primary purpose is to bridge industry-standard system buses such as AHB and AXI with SRAM memory, ensuring efficient, and timing compliant data transfers between processors, DMA engines, and memory subsystems.

With latency as low as three clock cycles, it enables high-speed memory access suitable for performance-critical applications. The Single-Port SRAM Controller integrates programmable memory addressing and built in address decoding logic, enabling flexible memory mapping and simplified SoC integration. Configurable read and write wait cycles allow designers to match SRAM timing characteristics across different process nodes and vendors, ensuring optimal compatibility and performance

Data integrity and selective memory updates are supported through byte-enable functionality which particularly valuable in processor-based systems where sub-word updates are frequent. The controller's fully synchronous logic design ensures clean timing closure, and simplified static timing analysis (STA), reducing integration risk and accelerating design cycles

Support for multiple SRAM chips allows scalable memory architectures, including banked memory systems and expanded address spaces. This makes the controller suitable for microcontrollers, AI accelerators, networking buffers, FPGA-based systems, and custom compute subsystems

The TrueSilicon's Single-Port SRAM Controller IP is delivered as a synthesizable RTL solution, optimized for power, performance, area (PPA), and latency. The IP is designed to integrate seamlessly into AMBA based infrastructures and can be paired with additional IP blocks such as DMA controllers, cache subsystems, or interconnect fabrics to form a complete memory subsystem solution

Figure 1 depicts the high-level architecture of the AXI Single-Port SRAM Controller, highlighting the AXI Bus interface unit, address decode logic, Driving and RAM State machine. This modular architecture enables SoC designers and OEMs to quickly integrate reliable SRAM access into their designs. In similar way, figure 2 represent high level architecture of AHB Single Port SRAM Controller

By combining configurability, low latency, burst support, and robust synchronous design, the Single-Port SRAM Controller IP delivers a scalable, production-ready solution for modern embedded and high performance systems
