The K4H280438B-TCB0 is a 256Mbit DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) chip manufactured by Samsung. It's designed for high-performance memory applications requiring substantial bandwidth and efficient data transfer. This particular chip is organized as 64M x 4 bits.
Applications:
- Graphics cards
- Desktop and laptop computers
- Gaming consoles
- Networking equipment
- Digital TVs
Features:
- High Bandwidth: DDR technology allows for double the data transfer rate compared to traditional SDRAM.
- Low Voltage Operation: Operates at a relatively low voltage (typically 2.5V), reducing power consumption.
- Double Data Rate: Transfers data on both the rising and falling edges of the clock signal.
- Clocked Data Strobe (DQS): DQS signal helps with data alignment and timing, improving signal integrity.
- Auto Refresh Mode: Automatically refreshes memory cells to prevent data loss.
- Programmable Burst Length: Allows for efficient data transfer by fetching multiple data bits in a single burst.
Benefits:
- Improved System Performance: High bandwidth and fast data transfer rates enhance overall system performance, especially in memory-intensive applications.
- Reduced Power Consumption: Low voltage operation contributes to lower energy consumption and longer battery life in portable devices.
- Increased Memory Capacity: Provides a large amount of memory for storing data and applications.
- Enhanced Data Integrity: Auto refresh mode and DQS signal ensure data is stored and retrieved accurately.
- Efficient Data Transfer: Programmable burst length allows for optimized data transfer based on application requirements.
Additional Details: The K4H280438B-TCB0 is typically packaged in a TSOP (Thin Small Outline Package). The specific operating frequency and timings can vary based on the exact specifications of the chip. Always refer to the official Samsung datasheet for the most accurate and up-to-date information. It also supports various power-saving modes to further reduce energy consumption when the memory is not actively being used. The TCB0 typically indicates the speed grade and temperature range, which should be carefully considered based on the application's requirements.
