A memory subsystem typically includes cache memory (often SRAM), main memory (DRAM), and non-volatile memory such as flash or ROM. These are organized hierarchically to balance speed, capacity, and power consumption.
Key parameters include memory capacity (1–64 MB), access time (10–70 ns), operating temperature (-40 to 85 °C), supply voltage (1.8–3.3 V), data bus width (8–64 bits), endurance (100k–1M cycles for EEPROM/Flash), standby current (1–50 µA), package type (BGA–QFP), operating humidity (5–95% RH), and ESD tolerance (2–8 kV per IEC 61000-4-2). Always confirm these values for the specific model.
Access time and data bus width directly impact how quickly the processor can retrieve data and instructions. Lower access times and wider buses improve throughput, which is critical for real-time digital signal processing and control functions.
The ESD tolerance is specified under the HBM model and references IEC 61000-4-2, with a range of 2–8 kV. This standard is a verification reference; actual compliance must be confirmed with the manufacturer.
