Display Driver IC With FIFO Memory Clock Domain Crossing

The graphic memory is divided into multiple banks (first bank, second bank, third bank, fourth bank) that can operate independently and simultaneously. Each bank handles specific data processing tasks, allowing parallel operation that increases overall data processing speed while maintaining manageable complexity through modular organization.

The patent introduces a time dimension to the memory architecture by implementing different operational modes (first mode and second mode) that switch between banks. This temporal dimension allows the system to achieve higher effective processing speed by utilizing multiple banks in sequence and parallel, overcoming the speed limitations of conventional single-bank architectures without proportionally increasing spatial complexity.

The high-speed data transfer task is segmented across multiple memory banks that operate in parallel. By distributing the data processing workload across four banks instead of using a single high-speed interface, the patent reduces the burden on any single interface component, thereby lowering power consumption and heat generation per interface while maintaining overall high data transfer speed through parallel processing.

The patent implements continuous data processing by switching between different operational modes that utilize different banks. While one bank is processing data, another bank can be preparing or transferring data, ensuring continuous useful action without requiring all components to operate at maximum power simultaneously. This continuous operation maintains high effective transfer speed while reducing peak power consumption and heat generation.
