Secure by Design Series: Inline Memory Encryption & MACsec: Protecting Data in Use and in Motion
https://event.on24.com/eventRegistration/EventLobbyServlet?target=reg20.jsp&eventid=5209466&sessionid=1&key=92AA2381476A4900595D2034C1824742&groupId=6549411&sourcepage=register#new_tab[Live on Feb 19] This webinar will examine two critical technologies that address these challenges: Inline Memory Encryption (IME) and MACsec (Media Access Control Security). We’ll explore how IME protects data as it moves between CPU and memory, defending against physical and side-channel attacks, while MACsec secures Layer 2 Ethernet communications against eavesdropping, replay, and […]
Port Dual-Mode
https://www.rambus.com/chip-interface-ip-glossary/port-dual-mode/Port Dual-Mode refers to the capability of a hardware interface port, commonly found in high-speed serial communication systems, to operate in two distinct protocol modes.
Parity Protection
https://www.rambus.com/chip-interface-ip-glossary/parity-protection/Parity Protection Table of Contents Definition How it Works Features Benefits Enabling Technologies Rambus Technologies What is Parity Protection? Parity Protection is a fundamental error detection technique used in digital systems to identify single-bit errors in data storage or transmission. It works by appending a parity bit to a data word, which indicates whether the […]
PAM3 and PAM4
https://www.rambus.com/chip-interface-ip-glossary/pam3-and-pam4/PAM3 and PAM4 Table of Contents Definition How They Work Differences Benefits Enabling Technologies Rambus Technologies What is PAM3 and PAM4? What is the difference? PAM3 (Pulse Amplitude Modulation with 3 Levels) and PAM4 (Pulse Amplitude Modulation with 4 Levels) are multi-level signaling schemes used in high-speed serial communication systems. Instead of binary signaling (NRZ), […]
Multi-Function
https://www.rambus.com/chip-interface-ip-glossary/multi-function/Multi-function enables a single PCIe device to perform multiple roles, improving integration, scalability, and virtualization in modern computing systems.
Multi-Port Front-End
https://www.rambus.com/chip-interface-ip-glossary/multi-port-front-end/A Multi-Port Front-End is a hardware or logic interface within a memory controller or data processing unit that enables simultaneous access to multiple data streams or clients. It acts as a high-bandwidth gateway, managing concurrent read/write requests from various sources—such as CPUs, GPUs, accelerators, or I/O subsystems—while maintaining data integrity, prioritization, and protocol compliance.
Multi-modal
https://www.rambus.com/chip-interface-ip-glossary/multi-modal/Multi-modal refers to systems, technologies, or models that can process and integrate information from multiple types of data sources or input modalities—such as text, images, audio, video, and sensor data. In computing and artificial intelligence (AI), multi-modal architectures are designed to understand and respond to complex, real-world inputs by combining insights from different data types.
MSI (Message Signaled Interrupts)
https://www.rambus.com/chip-interface-ip-glossary/msi/Instead of asserting a physical interrupt pin, a device sends a small memory write transaction to a predefined address in the host system. This write contains the interrupt vector, which the processor interprets as an interrupt request. MSI supports multiple interrupt vectors per device, allowing fine-grained signaling and better support for multi-core systems. The enhanced version, MSI-X, expands the number of vectors and adds per-vector masking and configuration.
Look-ahead Activate, Precharge, and Auto Precharge Logic
https://www.rambus.com/chip-interface-ip-glossary/look-ahead/Look-ahead Activate, Precharge, and Auto Precharge logic are advanced memory controller techniques used in DRAM systems (e.g., DDR4, DDR5, LPDDR5) to optimize memory access timing and throughput. These mechanisms anticipate future memory operations and prepare memory banks accordingly, reducing latency and improving overall system performance—especially in high-bandwidth applications like AI/ML, gaming, and high-performance computing (HPC).
FEC (Forward Error Correction)
https://www.rambus.com/chip-interface-ip-glossary/fec/Forward Error Correction (FEC) is a method used in digital communication systems to detect and correct errors in transmitted data without requiring retransmission. It works by adding redundant bits, known as error-correcting codes, to the original data stream. These codes allow the receiver to identify and fix errors caused by noise, interference, or signal degradation during transmission.
