Additional Details

The K4S641632E-TC80 features a 4-bank architecture, which allows for concurrent access to different memory regions, further improving performance. It supports auto-refresh and self-refresh modes for data retention. The 'TC80' suffix likely indicates the speed grade or temperature range of the part; refer to the Samsung datasheet for specifics. Detailed timing parameters, such as clock cycle time, row access time, and column access time, are crucial for proper system design and must be consulted in the datasheet. Proper decoupling capacitors should be used near the power pins to minimize noise and ensure stable operation. This specific chip has been used in legacy systems but may not be the first choice for new designs due to more modern memory alternatives (DDR, DDR2, DDR3, etc.).
