DATA CACHING FOR FAST SYSTEM BOOT-UP - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240303087 titled 'DATA CACHING FOR FAST SYSTEM BOOT-UP

The patent application describes methods, systems, and devices for data caching to enable fast system boot-up. A memory system creates a linked mapping of addresses, also known as a mixed page pointer table, which includes logical addresses associated with commands received during boot-up and their corresponding physical addresses. The linked mapping also tracks the frequency of each logical address being referenced during successive boot-up procedures. The memory device uses this linked mapping to predict which data will be accessed during boot-up and pre-transfers the data to volatile memory based on these predictions.

Questions about Predictive Data Caching for Fast System Boot-Up: 1. How does the linked mapping system improve system boot-up times? The linked mapping system allows for predictive data caching, which pre-transfers data to volatile memory based on past usage patterns, reducing the time needed to access critical data during boot-up.

2. What are the potential drawbacks of using predictive data caching in memory systems? One potential drawback could be the increased complexity of managing the linked mapping system and ensuring accurate predictions of data access patterns.

Original Abstract Submitted

methods, systems, and devices for data caching for fast system boot-up are described. a memory system may create a linked mapping of addresses, which may also be referred to as a mixed page pointer table. the linked mapping may include logical addresses associated with commands received during a boot-up procedure, and their associated physical addresses. the linked mapping may also include a counter associated with each logical address to track how often the logical address is referenced during successive boot-up procedures. over successive boot-up procedures, addresses may be added or removed from the linked mapping, and sequential addresses may be compressed. the memory device may use the linked mapping to predict which data may be accessed during the boot-up procedure, and may pre-transfer the data to volatile memory based on the prediction.
