摘要: An apparatus and method are provided for limiting a drop of a supply voltage in an SRAM device to retain the state of the memory during an IDLE state. The apparatus may include a memory array, a sleep device, and a clamping circuit. The clamping circuit may be configured to activate the sleep device when a voltage drop across the memory array falls below a preset voltage and the memory array is in an IDLE state.

摘要: An apparatus and method for generating a reference in a memory circuit are disclosed. At least two dummy bit-cells are used to generate a reference voltage. One cell has high value stored and the other has a low value stored. The cells are activated and discharged into respective bit-lines. The bit-lines are equalized during the discharge process to generate a reference that is approximately a mid point between a high value cell and a low value cell.

摘要: Some embodiments provide a memory cell comprising a body region doped with charge carriers of a first type, a source region disposed in the body region and doped with charge carriers of a second type, and a drain region disposed in the body region and doped with charge carriers of the second type. According to some embodiments, the body region, the source region, and the drain region are oriented in a first direction, the body region and the source region form a first junction, and the body region and the drain region form a second junction. Moreover, a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased. Some embodiments further include a transistor oriented in a second direction, wherein the second direction is not parallel to the first direction.

摘要: A short latency and high bandwidth memory includes a systolic memory that is sub-divided into a plurality of memory arrays, including banks and pipelines that access these banks. Shorter latency and faster performance is achieved with this memory, because each bank is smaller in size and is accessed more rapidly. A high throughput rate is accomplished because of the pipelining. Memory is accessed at the pipeline frequency with the proposed read and write mechanism. Design complexity is reduced because each bank within the memory is the same and repeated. The memory array size is re-configured and organized to fit within desired size and area parameters.
