The apparatuses each include a switching arrangement configured to selectively connect a group of one or more electrodes of the apparatus to a group of one or more circuits of the apparatus. Each electrode of the group may be selectively connected to multiple circuits each configured to provide a stimulation signal to the electrode concurrently, thus selectively increasing a range of amplitudes of an signal used to stimulate the electrode compared with a single circuit, and each configured to sense a signal from the electrode concurrently, thus permitting a signal-to-noise ratio (SNR) to be increased compared with a single circuit. The switching arrangement may be reconfigured to change a number of circuits connected to each electrode of the group, thus permitting the range to be further increased and the SNR to be further increased.

Abstract: Methods, systems, and devices for link startup sequence (LSS) mode detection for memory systems are described. A memory system may determine a duration between signals associated with a LSS and may use the duration to determine whether the LSS is associated with a first speed mode or a second speed mode. In some examples, the memory system may perform the LSS in accordance with the determined speed mode in response to determining that the duration satisfies a threshold. Performing the LSS may involve initializing the memory system. Further, the memory system may initiate a timer in response to receiving a first signal and may stop the timer in response to receiving a second signal and determining that a channel has transitioned from a first state to a second state. The speed mode may be a low speed LSS mode or a high speed LSS mode.
