Memory system with multi-level status signaling and method for operating the same
Abstract:
A memory system includes a status circuit having a common status node electrically connected to a respective status pad of each of a plurality of memory chips. The memory system also includes a plurality of resistors disposed within the status circuit to define a voltage divider network for generating different voltage levels at the common status node. Each of the different voltage levels indicates a particular operational state combination of the plurality of memory chips. Also, each of the plurality of memory chips is either in a first operational state or a second operational state. Additionally, the different voltage levels are distributed within a voltage range extending from a power supply voltage level to a reference ground voltage level.
