RAM

Volatile storage providing nanosecond-latency read/write for running programs.

Volatile storage providing nanosecond-latency read/write for running programs.

The OS partitions physical RAM into kernel space (privileged, hardware-facing) and user space (application sandboxes)

Bandwidth and latency dominate performance in data-intensive tasks — architecture addresses this with wide buses and high-bandwidth memory.

Embedded systems often use SRAM on-chip inside a MCU

On iPhones, RAM is stacked ON the MPU package (tiny footprint)

Windows allows RAM upgrading; macOS does not (RAM inside MPU package)
