Abstract

A data management system and method for storing data records of at least two different category types in a first non-volatile memory section, which may be flash memory, divided into sequentially arranged memory locations. The data records, each including its category type and a time stamp, are sequentially stored into memory locations indicated by a cyclic write pointer stored in a second nonvolatile memory section. A new node associated with a data record is added to a linked list stored in a volatile memory section for a determined category type, such that there is a separate linked list for each category type. The data management system may be included in a glucose meter of a blood glucose system, and use of the second nonvolatile memory section and the volatile memory sections allows data records stored in the first nonvolatile memory section to be displayed by category type and by time stamp more quickly.
