ABSTRACT:
A memory device includes a first memory bank and a second memory bank, each memory bank having at least one subarray of memory cells. Multiple sense amplifiers are coupled to at least one subarray of memory cells. At least one sense amplifier is configured for use by both the first memory bank and the second memory bank, but not simultaneously. The sharing of sense amplifiers between memory banks minimizes the die area penalty caused by additional memory banks. The memory device is configured such that the first memory bank is adjacent to the second memory bank.
