Additional Details

The K4B2G1646B-HCF7 operates at a specific voltage, typically 1.5V for standard DDR3. It uses a double data rate architecture to achieve high data transfer rates, effectively doubling the bandwidth compared to single data rate SDRAM. The chip is typically packaged in a FBGA (Fine-pitch Ball Grid Array) for efficient board mounting and signal integrity. Timing parameters such as CAS latency (CL), RAS to CAS delay (tRCD), and RAS precharge time (tRP) are crucial for proper memory operation and must be configured according to the manufacturer's specifications. Refer to the official Samsung datasheet for detailed specifications and timing diagrams. The HCF7 suffix likely denotes a particular speed grade and operating temperature range, which needs to be confirmed via the datasheet.
