Additional Details
The D4364C-12L is a DRAM that was commonly used in older electronic devices. DRAM requires constant refreshing to retain data, which adds complexity to the memory controller design compared to static RAM (SRAM). However, DRAM offers a higher density and lower cost per bit than SRAM, making it a suitable choice for applications where memory capacity is critical and power consumption is a concern.
Specific details about the supply voltage, refresh rate, and other electrical characteristics can be found in the manufacturer's datasheet. It is important to adhere to the recommended operating conditions to ensure reliable performance.
Due to advancements in memory technology, the D4364C-12L is considered a legacy component. Modern systems typically use larger capacity and faster memory technologies, such as SDRAM and DDR SDRAM.
