First Claim
Patent Images
1. A semiconductor memory device, comprising:
- a micro configured to output a data generating code according to a state checking operation command; and
a step code generating unit configured to generate a step code for an operation currently performed by a storage device according to the data generating code, and output ROM data including the step code,wherein the micro generates a state code for the operation currently performed by the storage device and an operation code for a segmentalized step of the operation according to the ROM data.
