Abstract: Methods, systems, and devices for compressing firmware data are described. A memory system may access firmware data associated with the memory system that includes bank data. The memory system may determine whether the bank data in the firmware data is compressed and, in cases that the bank data is compressed, the memory system may decompress the bank data prior to storing the bank data at a controller of the memory system. In some examples, a bank header in the firmware data may include information for the memory system to decompress the bank data. For example, the bank header may indicate the size of the compressed bank data associated with each bank. Additionally, the memory system may read the compressed bank data according to the indicated size and store the bank data at the controller or at a memory device of the memory system.
