摘要: A memory system having a selectable configuration for sense amplifiers is included. The memory system can include bit cells and a switch module coupled to the bit cell and to a first portion of a sense amplifier. The switch module can connect, disconnect or cross couple the bit cell to the sense amplifier based on a test for the input offset voltage of first portion of the sense amplifier. A similar configuration can be implemented by a second portion of the sense amplifier. The system can also include a programmer module to configure a setting of the switch module and can include a column select module to couple the bit cells to the sense amplifiers based on what column of bit cell is to be read. Other embodiments are also disclosed.

摘要: In general, in one aspect, the disclosure describes a memory array including a plurality of memory cells arranged in rows and columns. Each memory cell includes a transistor having a floating body capable of storing a charge. A plurality of word lines and purge lines are interconnected to rows of memory cells. A plurality of bit lines are interconnected to columns of memory cells. Driving signals provided via the word lines, the purge lines, and the bit lines can cooperate to alter the charge of the floating body region in one or more of the memory cells.
