EFFICIENT DATA PATH ARCHITECTURE FOR FLASH DEVICES
Efficient data path architecture for flash devices requiring multi-pass programming utilizes an external memory as an intermediate buffer to store the encoded data used for a first pass programming of the flash device. The stored encoded data can be read from the external memory for subsequent passes programming instead of fetching the data from an on-chip memory, which stores the data received from a host system. Thus, the on-chip memory can be made available to speed up the next data transfer from the host system.
COHERENCY MANAGEMENT FOR VOLATILE AND NON-VOLATILE MEMORY IN A THROUGH-SILICON VIA (TSV) MODULE
An aspect includes coherency management between volatile memory and non-volatile memory in a through-silicon via (TSV) module of a computer system. A plurality of TSV write signals is simultaneously provided to the volatile memory and the non-volatile memory. A plurality of values of the TSV write signals is captured within a buffer of the non-volatile memory corresponding to a data set written to the volatile memory. Storage space is freed within the buffer as the data set corresponding to the values of the TSV write signals stored within the buffer is written to a non-volatile memory array within the non-volatile memory.
Clock mode determination in a memory system
A clock mode configuration circuit for a memory device is described. A memory system includes any number of memory devices serially connected to each other, where each memory device receives a clock signal. The clock signal can be provided either in parallel to all the memory devices or serially from memory device to memory device through a common clock input. The clock mode configuration circuit in each memory device is set to a parallel mode for receiving the parallel clock signal, and to a serial mode for receiving a source synchronous clock signal from a prior memory device. Depending on the set operating mode, the data input circuits will be configured for the corresponding data signal format, and the corresponding clock input circuits will be either enabled or disabled. The parallel mode and the serial mode is set by sensing a voltage level of a reference voltage provided to each memory device.
Resistive volatile/non-volatile floating electrode logic/memory cell
A resistive floating electrode device (RFED) provides a logic cell or non-volatile storage or dynamic or static random access memory on an extremely compact matrix with individual cells scalable to the minimum available lithographic feature size regime by providing atomic switches connected in anti-parallel relationship, preferably with a common inert electrode. Programming is facilitated by limiting current to a compliance current level in order to maintain an OB state from which the cell can be written to either the 0 or 1 state. A perfecting feature of the invention provides for selective operation of a cell as a diode or in a volatile or non-volatile storage mode within the same memory array. A series connection of three or more RFEDs in accordance with the invention having different ON state currents, OFF state currents and reset currents can be used as adaptive, neural or chaotic logic cells.
