Description

具有記憶體封裝下之控制器之記憶體裝置及相關之系統及方法
所揭示之實施例係關於具有記憶體封裝及控制器之記憶體裝置。在一些實施例中，本發明係關於包含位於記憶體封裝之一堆疊下之嵌入式控制器之記憶體裝置。
快閃記憶體常用於儲存智慧型電話、導航系統(例如汽車導航系統)、數位相機、MP3播放器、電腦及諸多其他消費型電子裝置之資料。通用串列匯流排(USB)裝置、記憶體卡、嵌入式磁碟機及其他資料儲存裝置通常包含快閃記憶體，此係歸因於快閃記憶體之小外觀尺寸。電子裝置中之專屬記憶體控制器可管理儲存於快閃記憶體上之資料。不幸地，此等專屬記憶體控制器會減少電子裝置中之其他組件之可用空間。為減小電子裝置之大小，可將記憶體控制器整合至主機處理器中以(例如)增加其他電子組件之可用空間。例如，主機處理器可具有管理由快閃記憶體儲存之資料之整合記憶體控制器(IMC)，但此等IMC與特定類型之記憶體相容且通常無法支援新型記憶體，諸如針對未來標準(例如嵌入式多媒體卡(eMMC)標準規格之未來版本)而設計之新「反及」記憶體。由於IMC將電子裝置限制於特定類型之快閃記憶體，所以該等電子裝置無法使用具有較高儲存密度、改良效能或增強功能之新記憶體。
記憶體控制器亦可嵌入於多晶粒記憶體封裝內。例如，習知eMMC記憶體可為具有一嵌入式多媒體卡(MMC)控制器之一單一高容量「反及」封裝(例如具有堆疊晶粒之一「反及」封裝)。該嵌入式MMC控制器可使一主機處理器免於執行需要大量計算資源之「反及」記憶體管理(例如寫入、讀取、擦除、錯誤管理等等)。因為「反及」晶粒具有難以測試之小特徵，所以在封裝之前不測試個別「反及」晶粒。多晶粒「反及」封裝可經測試以識別待捨棄之不佳封裝(例如，具有壞「反及」晶粒之封裝)。不幸地，不佳「反及」封裝中之嵌入式MMC控制器亦被捨棄以導致製造成本增加。

下文將描述記憶體裝置及相關系統及方法之一些實施例之特定細節。術語「記憶體裝置」一般係指具有一封裝基板、一或多個多晶粒記憶體封裝及一控制器之一封裝。該控制器可定位於該等記憶體封 裝下且可對各記憶體封裝提供記憶體管理。在一些實施例中，記憶體裝置可為具有適合用於行動裝置(例如智慧型電話、平板電腦、MP3播放器等等)、數位相機、路由器、遊戲系統、導航系統、電腦及其他消費型電子裝置之多晶粒記憶體封裝之快閃記憶體(例如eMMC記憶體、通用快閃儲存器等等)。例如，該等多晶粒記憶體封裝可為(例如)快閃記憶體封裝，諸如「反及」封裝、「反或」封裝等等。熟習相關技術者亦應瞭解，本發明可具有額外實施例，且可在無下文參考圖1至圖6而描述之實施例之一些細節之情況下實踐本發明。
圖1係根據本發明之一實施例而組態之一記憶體裝置100之一橫截面圖。記憶體裝置100可包含一封裝基板104(「基板104」)、一控制器106及配置成一堆疊之第一、第二、第三及第四多晶粒記憶體封裝108a、108b、108c、108d(統稱為「記憶體封裝108」)。基板104可電耦合至控制器106及記憶體封裝108，使得控制器106介接於記憶體封裝108與一主機(例如一電子裝置之一主機處理器)之間，該主機與記憶體裝置100通信。控制器106可附著至基板104。在一些實施例中，控制器106可定位於記憶體封裝108之堆疊下，使得記憶體裝置100具有一相對較小佔用面積。
控制器106可處置記憶體管理，使得一主機處理器免於執行其他任務。在各種實施例中，控制器106可包含電路、軟體、韌體、記憶體或其等之組合且可經組態以管理快閃記憶體(例如「反及」記憶體、「反或」記憶體等等)。在一些實施例中，控制器106可為包含一半導體基板(諸如矽基板、絕緣體上矽基板、化合物半導體(例如氮化鎵)基板或其他適合基板)之一控制器晶粒，且可具有各種積體電路組件或功能特徵之任何者，諸如動態隨機存取記憶體(DRAM)、靜態隨機存取記憶體(SRAM)、其他形式之積體電路裝置(其包含處理電路、成像組件及/或用於管理記憶體或其他組件之其他半導體裝置)。例 如，控制器106可為經組態以與「反及」記憶體一起使用之一多媒體控制器晶粒(例如一MMC控制器晶粒)且可包含電路、暫存器、介面模組(例如用於與主機介接之模組，用於與記憶體封裝介接之模組等等)及/或用於提供所要功能之其他模組。
基板104可包含第一接合墊120及第二接合墊122。第一接合墊120可藉由第一接線140而耦合至控制器106之對應接合墊130，且第二接合墊122可藉由第二接線142而耦合至記憶體封裝108之各者之對應封裝接點132(識別一者)。在一實施例中，基板104係將控制器106電耦合至各記憶體封裝108之一單一中介層。基板104可包含(例如)具有電連接器144(以虛線示意性地展示)(諸如金屬跡線、通孔或其他適合連接器)之一印刷電路板、一多媒體卡基板或其他適合中介層。電連接器144可使控制器106、第一接合墊120及/或第二接合墊122彼此耦合及/或經由基板104之下側處之封裝接點150(識別一者)及互連件152(識別一者)而耦合至外部電路(圖中未展示)。互連件152可為凸塊接合件或其他適合連接特徵。
控制器106可藉由一黏著劑160而附著至封裝基板104。黏著劑160可為一黏著材料(例如環氧樹脂、黏膠(adhesive paste)等等)、一黏著疊層(例如膠帶、晶粒附著或切塊晶粒附著膜等等)或其他適合材料。第一記憶體封裝108a可藉由覆蓋控制器106及接線140之一黏著劑162而附著至基板104。接著，額外記憶體封裝108b至108d藉由黏著劑164而彼此附接。在一些實施例中，黏著劑160、162、164可包括相同或類似材料。黏著劑162可具有比黏著劑164厚之一厚度以接納控制器106與記憶體封裝108a之間之接線140之部分。黏著劑164之厚度可足夠大以確保接線142穿過相鄰記憶體封裝108之間之間隙166(被識別者)。記憶體裝置100可進一步包含一封裝殼115，其包括至少部分囊封記憶體封裝108及接線142之一囊封劑116。
圖2係根據本發明之一實施例而組態之一記憶體封裝108之一橫截面圖。記憶體封裝108可包含複數個記憶體半導體晶粒200(識別一者)及一記憶體封裝基板202(「封裝基板202」)。封裝基板202可包含複數個第一接合墊208a及複數個第二接合墊208b。第一接合墊208a可耦合至(例如，線接合至)一第一群組之半導體晶粒200(例如兩組之四個晶粒)之對應接合墊209a(識別一者)，且第二接合墊208b可耦合至(例如，線接合至)一第二群組之半導體晶粒200(例如兩組之四個晶粒)之對應接合墊209b(識別一者)。在一些實施例中，一陣列之接合墊208a電耦合至各半導體晶粒200之一陣列之接合墊209a。可基於各自接合墊209a、209b之組態、數目及大小而選擇接合墊208a、208b之組態、數目及大小。在一些實施例中，一列接合墊208b電耦合至各半導體晶粒200之一列接合墊209b。封裝基板202可包含(例如)具有電連接器(諸如金屬跡線、通孔或其他適合連接器)之一中介層、一印刷電路板或其他適合基板，該等電連接器包含用於將記憶體封裝108電耦合至基板104(圖1)之封裝接點132(例如接合墊)、互連件(例如凸塊接合件)及/或其他特徵。
圖2展示呈一垂直堆疊配置之半導體晶粒200，其中相鄰半導體晶粒200彼此橫向偏移。在其他實施例中，半導體晶粒200可直接垂直堆疊於彼此上(即，無任何橫向偏移)，或呈任何其他適合堆疊配置，且可由半導體基板(諸如矽基板、絕緣體上矽基板、化合物半導體(例如氮化鎵)基板或其他適合基板)形成。半導體晶粒200可為經切割或單一化晶粒且可具有各種積體電路組件或功能特徵之任何者，諸如非揮發性記憶體、快閃記憶體(例如「反及」快閃記憶體、「反或」快閃記憶體等等)、DRAM、SRAM、其他形式之積體電路裝置(例如處理電路、成像組件及/或其他半導體裝置)。儘管所繪示之記憶體封裝108包含16個記憶體晶粒200，但記憶體封裝108亦可為具有16個以上 或16個以下記憶體晶粒(例如一個晶粒、兩個晶粒、四個晶粒、八個晶粒、十個晶粒、二十個晶粒等等)之一多晶片封裝。可基於記憶體封裝108之所要儲存容量而選擇晶粒之數目。由於嵌入式控制器106可管理多個記憶體封裝，所以記憶體封裝之一或多者(例如所有記憶體封裝108)可不具有用於記憶體管理之任何嵌入式控制器晶粒。
記憶體封裝108可進一步包含由至少部分囊封半導體晶粒200之堆疊及接線之一囊封劑116(例如一熱固性材料、一環氧樹脂或其他適合材料)組成之一封裝殼215。封裝殼215可提供免受周圍環境(例如濕度)影響之遮蔽、電隔離(例如接線之間之電隔離)及/或在處置期間對內部組件之保護。
圖3A至圖3E係繪示根據本發明之一實施例之用於組裝各種製造階段中之記憶體裝置100之一方法的橫截面圖。一般而言，控制器106可耦合至基板104且接著第一記憶體封裝108a可耦合至基板104，使得控制器106定位於第一記憶體封裝108a與封裝基板104之間。額外記憶體封裝可堆疊於記憶體封裝108a上。在將記憶體封裝108電耦合至基板104之後，可由囊封劑116囊封記憶體封裝108。下文將詳細討論製造階段之細節。
參考圖3A，可沿基板104(例如具有電路之一矽晶圓)之一上表面240定位第一接合墊120及第二接合墊122，且可沿基板104之一下表面242定位封裝接點150。控制器106通常具有比封裝108小之一佔用面積，因此，控制器106可在堆疊封裝總成108之前附著且電耦合至基板104。有利地，控制器106及其電連接件(例如接線140)不會干擾記憶體封裝108之堆疊及附著。如圖3A中所展示，可將攜載黏著劑160之控制器106放置於基板104之上表面240上，使得控制器106與接合墊120、122隔開以提供用於線接合之足夠空隙。黏著劑160可為晶粒附著黏膠或一黏著元件，例如一晶粒附著膜或一切塊晶粒附著膜(分別 被熟習技術者稱為「DAF」或「DDF」)。在一實施例中，黏著劑160可包含一壓力凝固黏著元件(例如膠帶或膜)，當該壓力凝固黏著元件被壓縮超過壓力之一臨限位準時，該壓力設定黏著元件將控制器106黏著至基板104。在另一實施例中，黏著劑160可為藉由曝露於UV輻射而凝固之一UV凝固膠帶或膜。
圖3B展示將控制器106附著至基板104且形成第一接線140之後之記憶體裝置100。控制器106之對置橫向側可具有藉由接線140而耦合至對應接合墊120(例如一列接合墊120)之一陣列之接合墊130(例如一列接合墊130)。封裝108a可攜載呈適合於與接線一起使用之一「導線上膜(film-over-wire)」材料之形式之黏著劑162。在其他實施例中，可使用焊料或其他適合直接晶粒附著技術來將控制器106直接耦合至基板104。在此等實施例中，黏著劑162可為DAF或DDF。可將具有黏著劑162之記憶體封裝108a放置於基板104之上表面240上，使得記憶體封裝108a橫向向外延伸超過控制器106之周邊。因而，可在組裝期間將整個控制器106直接定位於記憶體封裝108a與基板104之間。黏著劑162之厚度可足夠大以防止記憶體封裝108a之一下表面243與接線140之間之接觸以避免損壞接線140。此外，可將接合墊120直接定位於記憶體封裝108a下以確保控制器106之電連接件不干擾後續線接合程序。
圖3C展示將記憶體封裝108a附著至基板104且形成第二接線142之後之記憶體裝置100。可使用黏著劑164來將第二記憶體封裝108b附著至第一記憶體封裝108a。額外記憶體封裝(用隱線展示記憶體封裝108c)可堆疊於記憶體封裝108上且電耦合至基板104。黏著劑164之厚度可經選擇以維持相鄰記憶體封裝108之間之一所要距離以避免損壞接線142。例如，黏著劑164可足夠厚以防止接線142與相鄰記憶體封裝108之間之接觸恰好位於此等接線142上。
圖3D展示已藉由接線142而將各記憶體封裝108電耦合至基板104之後之記憶體裝置100。各記憶體封裝108之對置橫向側可具有藉由接線142而耦合至對應接合墊122(例如一列接合墊122)之一陣列之接合墊132(例如一列接合墊132)。所繪示之記憶體裝置100具有四個記憶體封裝108。在其他實施例中，記憶體裝置100可攜載更多或更少記憶體封裝108，例如一單一記憶體封裝108、兩個記憶體封裝108、五個記憶體封裝108、八個記憶體封裝108、十個記憶體封裝108、十五個記憶體封裝108等等。記憶體裝置100除包含記憶體封裝108之一或多者之外，亦可包含其他封裝或晶粒，及/或可包含其他封裝或晶粒來代替記憶體封裝108之一或多者。可基於記憶體裝置100之所要功能及尺寸而選擇記憶體封裝及/或晶粒之數目、組態及配置。
記憶體封裝108可配置成一垂直堆疊，使得當自上觀察時，記憶體封裝108相對於彼此而居中。此一對準配置可提供具有一相對較小佔用面積之記憶體裝置100。在其他實施例中，垂直堆疊之記憶體封裝108可經彼此橫向偏移以提供用於接入接合墊132之增大空隙。可基於(例如)線接合程序或其他後續程序而選擇橫向偏移之方向及距離。記憶體封裝108可堆疊成其他配置及組態以提供具有所要總大小之封裝。
圖3E展示囊封劑116至少部分囊封記憶體封裝108之堆疊及接線142(識別一群組之接線)之後之記憶體裝置100。囊封劑116可包含(例如)一熱固性材料、一樹脂(例如環氧樹脂)或其他適合材料(其提供(例如)機械支撐、免受周圍環境(例如濕度)影響之遮蔽、及/或電隔離(例如接線之間之電隔離))。在一些實施例中，可由囊封劑116完全囊封記憶體封裝108及接線142。在囊封記憶體封裝108之後，處理可繼續至後續製造階段，諸如形成球形接合件、單一化、切塊或其他所要程序。
圖3A至圖3E之製程可提高產品良率，此係因為可在組裝之前測試個別組件。記憶體封裝108可經個別測試以確保各記憶體封裝108具有已知良好晶粒(KGD)。例如，各記憶體封裝108可經測試以測試記憶體晶粒108之各者(圖2)。有利地，記憶體封裝108之基板202(圖2)可具有適合使用標準測試設備來測試之相對較大連接件。具有KGD之記憶體封裝108可經選擇以用於組裝成封裝，同時可捨棄具有已知不佳晶粒之記憶體封裝108。據此，基板104及控制器106僅與良好記憶體封裝108組裝以提供高產率。此外，基板104可具有用於測試組裝之後之基板104、控制器106、記憶體封裝108及/或其他內部組件之一標準球柵陣列或其他適合特徵(例如測試墊)。可識別且捨棄有缺陷之記憶體裝置100。
圖4係根據本發明之另一實施例而組態之一記憶體裝置300之一橫截面圖。記憶體裝置300可包含大體上類似於結合圖1至圖3E而描述之記憶體裝置100之特徵的特徵。記憶體裝置300可包含藉由接線142(識別一組)而電耦合至封裝基板104之記憶體封裝108，且控制器106可藉由接線140(識別一者)而電耦合至封裝基板104。記憶體裝置300亦可包含記憶體封裝108a與基板104之間之一或多個間隔物310。間隔物310可為矽或其他適合材料之經切割或單一化部件，其經定尺寸以將第一記憶體封裝108a定位成略微高於控制器106及接線140。一黏著劑(例如黏膠、DAF、膠帶等等)可用於將間隔物310緊固至基板104及/或記憶體封裝108a。其他類型之間隔物310(諸如一b-階段樹脂)可用於使記憶體封裝108a與基板104隔開達一所要距離且用於緊固記憶體封裝108a。該b-階段樹脂可經固化以將記憶體封裝108a完全黏著至基板104。
囊封劑116可部分或完全囊封經堆疊之記憶體封裝108及接線142，且囊封劑116亦可延伸至第一記憶體封裝108a與基板104之間之 一空腔320中。空腔320可由間隔物310之側壁324、記憶體封裝108a之下表面243及基板104之上表面240界定。在製造期間，囊封劑116可流動至空腔320中以至少部分囊封控制器106及接線140，使得囊封劑116使將控制器106耦合至基板104之電連接件電隔離。
圖5係繪示根據本發明之一實施例之記憶體裝置之一實施方案的一方塊電路圖。一記憶體裝置500可為記憶體裝置100、300之一者或可包含大體上類似於記憶體裝置100、300之特徵的特徵。記憶體裝置500可為管理一主機502與記憶體封裝108之各者之間之資料傳送之一封裝。控制器106可經組態以提供記憶體控制且可包含用於提供功能之一或多個模組520。模組520可包含(但不限於)用於錯誤校正之錯誤校正碼(ECC)模組、用於錯誤偵測之錯誤偵測碼(EDC)模組、耗損均衡模組、用於將邏輯映射至實體區塊之位址映射模組、用於區塊管理(例如不佳區塊管理、備用區塊管理等等)之模組、錯誤復原模組、用於分區保護之模組、用於自控制器106啟動之模組或其他所要模組。控制器106可經由一匯流排510而與主機502介接且可包含經由一記憶體匯流排514而可操作地耦合至記憶體封裝108之一介面506。控制器106可為根據多媒體卡規格(例如規格版本4.4、4.41等等)而設計之一MMC控制器。在一些嵌入式多媒體卡(eMMC)實施例中，控制器106可具有一匯流排510，其提供雙向資料信號(例如用於單位元資料傳送、4位元資料傳送、8位元資料傳送等等之資料信號)，自主機502接收命令信號，對主機502作出回應，及/或時控用於使匯流排傳送同步之信號。
主機502可包含具有處理能力之一裝置且能夠與記憶體裝置500介接。主機502可為一行動裝置之一組件(例如主機控制器、硬體、處理器、驅動器等等)、一個人電腦、一遊戲機或能夠將命令輸入提供至記憶體裝置500之其他電子裝置。控制器106可基於來自主機502之 命令輸入而管理資料(例如寫入、讀取、擦除資料)。
本文所描述之記憶體裝置之任何者可併入至諸多更大及/或更複雜系統之任何者(諸如圖6中所示意性地展示之系統600)中。系統600可包含一記憶體裝置602、一電源604、一主機606(例如I/O驅動器)、一處理器608及/或其他子系統或組件610。記憶體裝置602可為記憶體裝置100、300、500之一者或包含大體上類似於上文所描述之記憶體裝置之特徵的特徵。主機606可包含大體上類似於圖5之主機502之特徵。所得系統600可執行各種功能之任何者，諸如記憶體儲存、資料處理及/或其他適合功能。據此，代表性系統600可為(但不限於)手持式裝置(例如行動電話、平板電腦、數位閱讀器及數位音訊播放器)、電腦、數位相機、電器及車輛(例如汽車、輪船、飛機)。系統600之組件可容納於一單一單元中或分佈於多個互連單元中(例如，透過一通信網路)。若記憶體裝置602係可移除的，則其可由另一記憶體裝置(例如具有更先進功能之一新記憶體裝置)替換。記憶體裝置之各者可具有一嵌入式控制器，其經組態以管理記憶體來避免主機606與內建記憶體之間之不相容。
可基於電子裝置之大小而選擇本文所揭示之記憶體裝置之大小。例如，圖1之記憶體裝置100或圖4之記憶體裝置300可具有約4mm至約7mm之一範圍內之一高度、約13mm至約17mm之一範圍內之一寬度及約17mm至約25mm之一範圍內之一長度。記憶體封裝108(參閱圖1及圖2)可具有約0.75mm至約1.5mm之一範圍內之高度(例如1.2mm)、約12mm至約16mm之一範圍內之寬度及約16mm至約20mm之一範圍內之長度。

本文所揭示之至少一些實施例係包括一封裝基板、具有半導體晶粒之複數個堆疊記憶體封裝、一控制器及一囊封劑之一記憶體裝置。該控制器附著至該封裝基板且定位於該等記憶體封裝與該封裝基板之間。該控制器經組態以管理該等記憶體封裝之各者。該囊封劑由該封裝基板攜載且囊封該等記憶體封裝之一或多者。
