摘要:
A flash memory chip that can be switched into four different read modes is described. In the first read mode, asynchronous flash mode, the flash memory is read as a standard flash memory where the reading of the contents of a first address must be completed before a second address to be read can be specified. In the second read mode, synchronous flash mode, a clock signal is provided to the flash chip and a series of addresses belonging to a data burst are specified, one address per clock tick. Then, the contents stored at the addresses specified for the burst are output sequentially during subsequent clock ticks in the order in which the addresses were provided. Alternately, if a single address is provided to the flash chip when it is in the synchronous mode, the subsequent addresses for the burst will be generated within the flash chip and the data burst will then be provided as output from the flash chip. In the third read mode, asynchronous DRAM mode, the row and column addresses are strobed into the flash memory using strobe signals. The flash memory then converts the row and column addresses internally into a single address and provides as output the data stored at that single address. The flash memory does not need an extended precharge period or to be refreshed, but can be controlled by a standard DRAM controller. In the fourth read mode, synchronous DRAM mode, the flash memory emulates a synchronous DRAM.

An asynchronous nonvolatile memory includes a plurality of individual memory components. A burst read operation references consecutive addresses beginning with a first address, wherein the consecutive addresses are not located in a same memory component. A method of performing a burst read operation in the asynchronous nonvolatile memory includes the step of providing the first address as a current address to the plurality of individual components. A current page identified by m higher order bits of the current address is selected. Each of the individual memory components senses a location identified by the m higher order bits. An output of a selected individual memory component is enabled in accordance with n lower bits of the current address. A consecutive subsequent address is provided, wherein the current address becomes a preceding address and the consecutive subsequent address becomes the current address. The output of another selected individual memory component identified by the n lower order bits of the current address is enabled without generating wait states, if the current and preceding addresses identify a same page. The process of providing consecutive subsequent addresses and enabling the output of a memory component identified by the n lower order bits is repeated as long as the current and preceding addresses identify the same page.

A storage container that includes walls having complimentary-shaped edges with complex edge profiles. The complex edge profiles of adjoining walls mate with each other to form an interface that defines a thermal leak path between a storage area of the container and an exterior environment. The thermal leak path has a length that is greater than the thickness of the adjoined walls. In one example, the complex edge profile includes step-shaped features. The walls may also include one or more overlapping super-insulating panels. The panels may be joined to one another with adhesive layers. The super-insulating panels may be also be disposed in a wall including interior and exterior linings that are joined and sealed to define a space between the linings. The space may be evacuated and optionally filled with a super-insulating gas.

An insulating liner for an article of clothing includes a first layer, a second layer attached to the first layer, and an insulating layer sealed between the first and second layers, wherein the insulating layer is composed of an aerogel material. The first and second layers can be a PVC foam hermetically sealed about the aerogel material by welding. In a preferred embodiment, the insulating liner is a shoe liner that includes a polyester wearing material adhered to the top layer of PVC foam. A method of forming the insulating liner is also provided.

A headgear assembly including a flexible cap and an insulator adapted to increase the heat retention of the cap. The cap includes an interior surface and a peripheral edge which surround and define a hemispherical interior cavity. A sweatband is affixed to the peripheral edge of the cap and is located adjacent the interior surface of the cap. The insulator is disposed within the interior cavity of the cap and includes a peripheral edge disposed between the band and the interior surface of the cap which retains the insulator within the cap.
