Memory IC FAQ

How is Partial Array Self Refresh configured?

PASR is configured using the Extended Mode Register, allowing selection of full bank, half bank, or quarter bank self-refresh coverage to reduce power consumption.

What determines the burst wrap behavior?

Burst wrap behavior is determined by the programmed burst length and starting column address, ensuring accesses remain within the selected block boundaries.
